Why URL Shorteners Are a Bad Idea for Email Marketers

Friday, February 3rd, 2012

Here at Real Magnet, the deliverability team scours through bounce logs on a daily basis to gather details as to why our customer’s emails are bouncing. One bounce trend that we continue to see is customers that use URL shorteners in their email marketing content. Many major blacklists have blacklisted URL shorteners like goo.gl and hotshorturl.com and networks will block those emails that contain them.

URL shorteners are a service, paid or free, where you enter in the full URL in a text box and it will shorten it. The shortened URL will point to the same site as the original URL, but the URL will be a lot shorter. Social networking sites that have a character limit can benefit from URL shorteners. The problem with that is many spammers also use this service to point to a malicious web site that may install a virus, malware, and/or steal information from you. Spammers are also creating their own URL shorteners and using them when their current shortener gets blacklisted. The issue is the end user that clicks the URL shortener link will not know where the link takes them until the page and full URL has loaded.

For email marketers, getting your emails delivered is of utmost importance. Testing your content and URLs should be a part of your email marketing plan. Remember to use full URLs when you can and avoid URL shorteners. Until next time, stay relevant, stay engaged, and get delivered!

Chris Arrendale Joins EEC Deliverability & Compliance Roundtable

Friday, January 27th, 2012

Chris Arrendale, Real Magnet’s Senior Director of Deliverability & ISP Relations, covers for our clients some of the bigger deliverability issues right here on the blog, and also on Twitter at @Arrendale. And now he is expanding his deliverability purview industry-wide as an invited member of the Email Experience Council’s Deliverability & Compliance Roundtable.

Chris’ role on the roundtable is not unlike what we task him with here – act as a liaison between the sending and receiving community with the aim of keeping the lines of communication open and working towards standards that make email work better for all of us. The difference is that the EEC helps amplify senders’ voices by expressing concerns with the collective weight of many organizations. Chris’ role also includes Real Magnet in standard-setting conversations from the very outset, giving us – and our clients – greater visibility into the trends shaping email, and how they will impact our day-to-day lives as email marketers.

The Roundtable doesn’t just meet and talk, however. Every year they produce a new research report or whitepaper on the issue they’ve identified as central to email deliverability and compliance. Previous reports include “How to Revive a Stale Email List,” “The Deliverability Resource Guide,” and “The State of Email Metrics.”

The Roundtable meets every third Thursday. We expect a full report, Chris.

Email Deliverability Numbers from 2011

Friday, January 20th, 2012

I have to admit, I was really impressed with the figures in the article “Internet 2011 in numbers” (http://royal.pingdom.com/2012/01/17/internet-2011-in-numbers/).  Of course, I paid close attention to the email numbers, but the other trends they discuss in mobile, social media, and domain names were also fascinating. Here’s the list that caught my attention:

  • 3.146 billion – Number of email accounts worldwide.
  • 27.6% – Microsoft Outlook was the most popular email client.
  • 19% – Percentage of spam emails delivered to corporate email inboxes despite spam filters.
  • 112 – Number of emails sent and received per day by the average corporate user.
  • 71% – Percentage of worldwide email traffic that was spam (November 2011).
  • 360 million – Total number of Hotmail users (largest email service in the world).
  • $44.25 – The estimated return on $1 invested in email marketing in 2011.
  • 40 – Years since the first email was sent, in 1971.
  • 0.39% – Percentage of email that was malicious (November 2011).

I’m not going to go into all the numbers and trends, but some of the items caught my eye and I wanted to dig deeper into them. Symantec reports that in November 2011, spam accounted for almost 71% of email traffic (down 3.7% from October 2011). If you couple that with the article’s number of 19% of spam emails are delivered to corporate email inboxes despite spam filters, spam can cause companies a lot of money in storage and lost productivity. Email marketers need to continue delivering relevant content to engaged subscribers to get into their subscriber’s inbox. I would also venture to take that a step further and make sure that email marketers are paying attention to their IP and domain reputation to make sure that they stay out of these email filters.

I also found it noteworthy to mention that the article stated Hotmail was the largest email service in the world with over 360 million users. Hotmail (which also includes msn.com and live.com domains) has come a long way in the past 15 years.  With the new “Sweep” feature, SkyDrive integration, and ActiveViews, I can see why Hotmail is growing. As someone in the deliverability space, I use Hotmail’s Smart Network Data Services portal (https://postmaster.live.com/snds/) on a daily basis to keep track of how my customers are performing at the Microsoft domains. The tools that Microsoft provides to the email world has made a difference in many customer conference calls concerning email deliverability.

The last point that I want to mention is the article states that there are 3.146 billion email accounts worldwide. That is an astonishing figure to me considering the first email was sent almost 40 years ago! I have seen figures where that number is expected to grow over 4 billion by 2015. As an email marketer, it is so important to remember that your list hygiene and data security practices are high priority. Continually segmenting your list and removing those inactive accounts will help with your email delivery.

Who says that email is dying?  Stay relevant, stay engaged, and get delivered!

Email Deliverability New Year’s Resolutions

Friday, January 13th, 2012

While many of us are making personal New Year’s Resolutions such as losing weight (myself included), finding a new job, or going back to school, email marketers should also be making a New Year’s Resolution concerning deliverability.  A new year means a new look on your email marketing program.  So, for your first email marketing meeting of the year, make sure you include these in your “resolution” checklist:

-User engagement is now more vital than ever.  Depending upon your business and sending methodology, identify subscribers that have been inactive for 6-9 months, and segment them out.  Removing the unengaged subscribers will help reduce complaints, improve your response rates, and help establish a stronger reputation with the ISPs.

-URL shorteners are not your friend!  Many URL shorteners are listed on major blacklists and will get your emails blocked, so always use full URLs in your campaigns.

-It is time to authenticate with SPF and DKIM.  If you do not have IP and domain authentication set up for your email program, resolve to get this done for 2012.

-Set up and monitor abuse@ and postmaster@ email addresses for your email sending domain.  This way people can get in contact with you if they have questions.  With that being said, monitor the reply email address too.  Nothing is as bad as trying to reply to a brand’s email only to find out that mailbox isn’t monitored.

-Resolve to test, test, and test your email marketing campaigns.  If you are a Real Magnet customer, we have deliverability tools for rendering, usability, and spam checking.

The key to success is to make sure you don’t just do all of the above once, but to continually look back at your email marketing program and make adjustments as needed.  I hope your New Year is prosperous and you strive to keep all of your New Year’s Resolutions!  Until 2013…

Whose Address Is It Anyway? The Pitfalls of Subscriber Sharing

Tuesday, May 3rd, 2011

It is not uncommon for a company or association to operate under several brands. For example, a publishing company may have a dozen or more different titles, and an association might have several different divisions. One of the potential advantages for this type of organizational structure is the opportunity to cross-market: the publishing company can sell its subscribers on some of its related titles, and the association can program its conferences so that they appeal to members of several of its divisions instead of just one. Email plays a big role in these cross-marketing efforts, but organizations should be aware of some of the potential pitfalls of email cross-marketing and subscriber sharing.

Is it legal?
If Publication A has enlisted an email subscriber, who actually owns the permission to email that person – Publication A, or the parent organization? It depends on what the CAN-SPAM law defines as “Affirmative Consent.” According to the provision, an email address can be shared by multiple parties as long as there is “clear and conspicuous notice at the time the consent was communicated.” You have seen this in practice, I’m sure. When you sign up for an email list you might see two options, such as “( ) Please subscribe me to email communications from ABC Company” and “( ) Please send me offers from partners and affiliates of ABC Company”. In our publishing example above, if the subscription option says “( ) Please subscribe me to email communications from Publication A” then only Publication A can mail to that subscriber. If cross-marketing is an objective, the publisher would need to change the language to clearly communicate that Publication A and other publications owned by Publication A’s parent company will email the subscriber. Alternatively, the organization might employ a second subscription option reading “( ) Please also send me communications from other Parent Organization titles that are relevant to me.”

Does being legal make it acceptable?
Your organization may follow all the CAN-SPAM rules to the letter, providing “clear and conspicuous notice at the time the consent was communicated” without fail, giving you every legal right to cross-market to your heart’s and division budgets’ content. But your objective with Affirmative Consent is not simply to abide by the law; it is to ensure that your subscribers anticipate all of the communications that you send them. If someone subscribing to Publication A signs up for email from sister publications at the same time, it does not necessarily mean that the subscriber will realize she has a relationship with your other titles, or recognize them when they show up in her inbox. If this happens, even though you’re on solid legal footing, your subscriber could ignore the message, delete the message, unsubscribe, or even mark it as spam. Being legal may make you right, but being right won’t guarantee you are successful.

Subscriber sharing pitfalls
So what happens if a cross-marketed subscriber doesn’t respond as intended to a message from another part of the organization?  No matter what her response, it has ramifications on the rest of your email program. Here’s how:

- If she ignores or deletes the message, that means she has had no engagement with it whatsoever. Increasingly, deliverability is impacted by engagement metrics. As greater percentages of subscribers fail to interact with messages, a sender’s reputation will begin to drop, which makes it harder for any messages to any subscribers to get through. This is a change over the past year. Previously, there was no danger in emailing to unresponsive list segments; today and in the future, there is a deliverability penalty to be aware of.

- Unsubscribing means that she would no longer receive messages from the cross-marketed publication, which is ideal for the reason above – it means you are no longer mailing to this unresponsive address. But she may also unsubscribe from all the organization’s lists, either wittingly or not. This means that not only is the opportunity to cross-market gone, but the original publication that earned her permission in the first place can no longer mail to her.

- Marking a message as spam is particularly problematic for business-to-business emailers and trade associations. When a subscriber marks a message a spam, an internal email administrator or spam monitoring service is notified. When it happens often enough, the sender could be blacklisted from the subscriber’s entire domain. In the case of b-to-b, this would mean that the publication can no longer reach this subscriber or any of her colleagues. And depending on how the sender’s IP addresses are structured, it could mean that none of the publications can reach any of the people at that particular organization. The sender could become invisible to the entire company.

How to avoid the pitfalls
The best way to avoid these pitfalls is to over-communicate. When your subscribers sign up, tell them clearly what they’re in for. When you send a cross-marketing message from an organization they do not have a direct relationship with, use the opening copy of the message to tell them why they are getting this message, and make it very easy for them to unsubscribe just to this type of message, keeping their original relationship with your organization intact. Remember, your objective is not solely to remain above the law; it’s to nurture and grow your relationships with your subscribers.

An Engagement Proposal

Tuesday, February 8th, 2011

Andrew Barrett is Sr. Director, ISP Relations & Deliverability for Real Magnet

For all of the vast resources the big four free inbox providers (Yahoo!, AOL, Gmail and MSN/Live/Hotmail) have expended over the decades to tweak, test and improve their filtering and delivery processes, they’ve been remarkably quiet about it. But their reticence is for good reason; if they were to publish the juicy details, they’d be undermining their own efforts, as spammers would surely make use of the information to evade filtering changes almost as soon as they are implemented.

So when a major inbox provider actually publishes specific details about how they make delivery decisions – as Gmail recently did in a paper explaining how Priority Inbox works – it creates a splash in the deliverability pond.

In January, Google posted on one of its research blogs a four page document containing the mathematical algorithms Gmail employs to decide how important any particular message is to its recipient by gauging the probability that the recipient will act quickly on the message.

It’s nothing short of a mathematical model of recipient engagement.

The real utility of the paper, in my opinion, is that it gives senders a clearer picture of what engaging e-mail looks like to the ISPs. I propose that Priority Inbox is a reasonable proxy for any recipient domain where it comes to measuring engagement. Senders who test and optimize their mail for preferred placement in the Gmail Priority Inbox should see gains in deliverability most anywhere else.

So what does engaging e-mail look like to Gmail? I’m not mathematically savvy enough to evaluate the algorithms in the paper, but the author provides some useful narrative:

Labelling: First, mail that the recipient marks as important is definitively important. The real trick, as the author notes, is how to infer importance without explicit recipient labelling. To do that, the algorithms measure hundreds of “features” of the message that fall roughly into one of three categories: Social, Content, and Thread features.

Social features: This has nothing to do with content-sharing activity on social networks, as some might assume. Instead, it’s a measure of the degree of interaction between the sender and the recipient, like the percentage of a sender’s mail that is opened by the recipient.

Content features: Gmail looks for keywords in the content, header and subject lines of the message that correlate with higher opens (or lack of opens).

Thread features: Gmail looks at aspects of the thread (or “conversation”) to which the message belongs. Has the recipient taken action on other messages in the same thread? If so, what percentage of the overall number of messages in the the thread were acted upon? Did the recipient actually start the conversation? If so, then Gmail assumes the message is important.

Beyond a treatment of the features of a given message, the author addresses a pair of interesting aspects:

Important or merely interesting: Opening a mail is a strong signal of importance to Gmail, but the author notes that many users also open a lot of mail that is “interesting” rather than “important”. So Gmail’s math tries to calculate where to draw the line between the two.

Time to action: The real goal of all the math is to predict the probability that a recipient will act on the mail within a given number of seconds following delivery to the inbox. The less time it takes, the more likely the mail is to be scored as “important”.

Part of the problem, of course, is that where Gmail places the message in the inbox directly affects how long it takes the recipient to notice and act on the message. Gmail tackles this, too, but at this point in my reading of the paper, my slide rule burst into flames.

This mathematical treatment of engagement metrics offers a rare glimpse beneath the kimono of a major inbox provider, and it confirms in a general sense much of what the deliverability community has been able to infer largely through observation: engagement metrics are playing an increasingly large role in automated delivery decisions at recipient domains. Senders who are serious about improving delivery (and, ultimately, ROI) will test and optimize their mail for engagement.


Half-True Predictions

Tuesday, January 18th, 2011

The thought of blogging predictions for the New Year in Deliverability makes me cringe. I’m not exactly sure why; it may have something to do with the fact that everyone else has already done it – we’ve had a bumper crop so far this year. Mostly, I think, I’d hate to be proven wrong later. So, instead of offering my own predictions (which would doubtlessly sound much like anyone else’s), I’d like to take a look at two different trends in deliverability that came only half-true in 2010, but that are still worth your time to continue to watch in 2011. The two trends are Domain Reputation and Engagement Metrics.

If you can recall what it was like to switch mobile carriers before the winter of 2003, you’ll understand why domain reputation is a big deal. If you wanted to switch carriers then, you had to get a new mobile number, because the local number portability rules for cell phones hadn’t yet been enacted. Coworkers, friends, relatives, and vendors all had to be notified of the change if you wanted them to stay in touch with you. It was a royal pain — painful enough in many instances to keep folks from switching carriers in the first place.

Today, sender reputation is largely associated with the IP address from which e-mail originates, and not with a business or brand. If a sender wants to migrate their e-mail program off of the desktop onto a hosted platform (like Real Magnet), or change ESPs, they’ll have to leave their sender reputation behind and start from scratch because the move means they’d be sending from an entirely different IP address.

Domain reputation is like local number portability: a reputation score is associated with sending domain (e.g., mail.yourbrand.com) instead of a dotted quad (209.108.90.17). On an Internet in which reputation is assigned to a domain rather than to an IP address, sender reputation can follow the company or brand, for better or worse, across changes in originating IP address.

Domain reputation was one of the hot new things that was supposed to gain traction in 2010, but that mostly didn’t. To be sure, ISPs are filtering on domains and URLs in the content of e-mail messages (for sites that are known to host malware or to be associated with spam, for example) but that are not necessarily domains that belong to the sender. Some of the big free inbox providers use their own, internal sender domain reputation systems for filtering, but these are still miles away from the kind of granular reputation scoring data that is available for IP addresses.

One key reason why domain reputation hasn’t enjoyed widespread adoption is because it relies on the use of sender authentication protocols to tie reputation to the sender, and lots of senders aren’t bothering to implement those protocols. But just last week, the smart folks at Gmail announced that businesses who host their mail on Google Apps can use DKIM, a particularly flexible authentication protocol, just by ticking a box in their application settings. If other large mail hosts follow suit, domain reputation has a chance to pick up steam in 2011.

The other prediction that became only half-true is the broad adoption of detailed engagement metrics by ISPs for automated deliverability decisions. Hotmail and Gmail made a huge splash last year by incorporating some engagement metrics in their filtering processes. Priority Inbox at Gmail, and Sweep at Hotmail/Live give preferred delivery – and even preferred positioning within the inbox – to mail that the recipient has opened or clicked through from before.

But beyond those two standouts, and only in a fairly limited way, none of the other large ISPs or reputation scoring firms seems to have done much more than experiment with collecting and using the data. The incremental improvement to their existing filters does not appear to have justified the huge overhead associated with the collection and management of all the additional data. For a time, we’d heard that ISPs were measuring all kinds of engagement metrics – like social network sharing activity, and even how long a recipient appears to spend reading messages from a given sender. But beyond the opens, clicks and spam complaints, other engagement metrics just don’t seem to be all that much more useful for deliverability.

That’s not to say that senders don’t need to worry about engagement – engagement remains incredibly important. Those clicks, opens and complaints remain significant components of sender reputation. Tracking engagement is critical to improving ROI. Senders who perform even a modicum of content or subject line testing gain incredible insight on how recipients are interacting with their mail, and can learn much about what will generate the best conversion rates. But when it comes to getting into the inbox, detailed engagement metrics do not appear to be on track to becoming as important to recipient domains as blocklists, content filtering, and IP reputation scores.

Detailed engagement metrics and domain reputation scoring are two big trends of 2010 that happened only half-way. But don’t get me wrong – they remain important concepts for deliverability, and successful senders will keep their eyes open for broader adoption in 2011.

Street Legal E-mail

Tuesday, January 4th, 2011

In this third set of questions following our recent deliverability webinar, we’ll try to clarify some confusion about the current legal state of affairs where bulk commercial e-mail is concerned. We’re also about to see some big changes go into effect in Canada that may have some impact on your e-mail strategy. We received this question from a webinar participant after the live session (if you haven’t caught it yet, you can still see the recorded version):

My e-mail is CAN SPAM compliant, but it still gets bounced or filtered. It’s not spam if it complies with the law, right?

First, let’s be clear: CAN SPAM does not actually make spam illegal, a common misconception among businesses that are new to e-mail marketing. Here’s a quick, simplified checklist of what the law actually requires of bulk commercial e-mail soliciations:

Don’t lie about the content or the source of the mail: If you’re sending an advertisement for a product or service, it has to be obvious that you’re mail is a solicitation. For example, senders can’t send mail purporting to contain photos from an uncle’s birthday party, when it really contains a sales flyer.

Provide clear instructions for opting out: Online opt-outs must use a single web page to accomplish the unsubscribe request. Forcing recipients to log into an account before they can opt-out is a no-no. Any opt-out mechanism (like an unsubscribe link) must remain functioning for at least 30 days, and opt-out requests must be honored within 10 business days.

Tell recipients where you are: Senders have to include a valid physical postal address in the body of the e-mail. Your business location or headquarters should appear here. A registered post office box is fine, too, as are any of the mailbox rental firms that are established under Postal Service regulations.

Perhaps what’s most notable about this short list of requirements is what’s missing: a prohibition from sending spam (howsoever one chooses to define the term). So, even if your mail is fully CAN SPAM compliant, that doesn’t necessarily mean to the ISPs or to recipients that your mail must not be spam. In fact, ISPs see millions of unsolicited bulk e-mail messages (a common definition of spam) every day that fulfills each requirement imposed by CAN SPAM, and they devote enormous resources to filter it.

So, CAN SPAM requirements actually represent the bare minimum for e-mail marketing standards, not the guarantee of delivery to the inbox that most newcomers assume it should be. To answer the question directly, then: mail that is CAN SPAM compliant can still be filtered or bounced by ISPs. In fact, CAN SPAM includes separate language that holds ISPs harmless when they filter mail.

What about the new Canadian spam law? Do senders in the U.S. have to abide by the law if they send to recipients in Canada?

Canada recently passed the world’s most stringent anti-spam law late last year, covering a broad range of electronic messaging, and it is expected to take effect in September of 2011. The Canadian law does what CAN SPAM never did: it requires senders of e-mail within or into Canada to have or to obtain explicit permission from their intended recipients. For most ISPs and recipient domains, it is a lack of permission that turns ordinary commercial e-mail into spam.

In theory, the Canadian law is enforceable in the U.S., though it wouldn’t be cheap or easy. Canadian plaintiffs would have to obtain a judgement in Canada, then find a court with jurisdiction in the U.S. that’s willing to enforce it. This requires a great deal of time and expense, so enforcement is likely to be rare. But if you’re already CAN SPAM compliant, and have implemented other best common sender practices, you’re likely already in compliance with the Canadian law (once it takes effect). Check my earlier blog post for a more complete analysis of the Canadian law.

That wraps up our brief look at spam laws in the U.S. and Canada. In our next installment of the deliverability webinar questions series, we’ll look at various types of content filtering, and what senders can do test their content for optimal deliverability.

Getting a Handle on Soft Bounces

Tuesday, December 21st, 2010

Welcome to the second in a series of posts focusing on questions we received from participants during and after our recent webinar on the topic. (If you missed it, we’ve posted a recorded version online, and we’ll announce when we’ve scheduled our next live deliverability webinar.) Last time, we talked about open rates and metrics. Today’s questions focus on soft bounces. After the webinar, an attendee e-mailed me the following question:

How many times should a recipient soft bounce before I suppress them?

Before we delve too deeply for an answer, it’s worth taking a moment to explain what a generic soft bounce is, and what the recipient mail server may be trying to tell you when they send it.

A generic soft bounce often indicates a temporary deferral, or de-prioritization of your e-mail. Unlike specific bounce types (e.g., user not found, mailbox full), a generic soft bounce does not indicate a recipient-specific condition. Rather, generic soft bounces are a sign that the receiving ISP has a problem with the mail or with the sender.

It often happens that, in the middle of the server-to-server transaction in which mail is presented to the recipient domain for delivery, the receiving server decides that it has accepted all of the mail it is prepared to accept during the current transaction. The balance of the mail in that transaction is then soft bounced, without any additional resources consumed by processing or filtering the mail, and with no regard to the recipient address, deliverable or otherwise.

There’s a range of possible reasons why an ISP will generic soft-bounce mail. Some of the major free inbox providers – like Microsoft Live Hotmail and Yahoo! – limit the volume of mail it will deliver from a sender during a given period of time based on reputation, how many messages in the send are addressed to non-existent accounts, and other considerations. Once that limit is exceeded, they’ll bounce any additional mail until the rate falls below the limit.

ISPs are very reluctant to share how they calculate these types of limits, because they don’t want bad actors to use that information to game their systems and evade their filtering processes. Instead, senders should try to implement those practices that improve sender reputation, so these limits can be raised or lifted entirely.

So, back to the question at hand: the generic soft bounce rate should not be a consideration in a decision of whether to suppress a particular recipient address. If you’re seeing a large number of generic soft bounces even after resend attempts, take it as a sign that it’s time to focus on best sender practices.

A follow-up question: what about “mailbox full” bounces?

Unlike the generic soft bounce, the “mailbox full” soft bounce is specific to an individual recipient e-mail address, and it means pretty much what it says: the mailbox is full, and any additional messages addressed to it will continue to bounce until the owner makes room by deleting some mail or adding capacity.

Senders can continue to send to recipients that bounce with a “mailbox full” message, but these bear very close scrutiny. A full mailbox can be a sign of an abandoned account (or one that is about to be abandoned), especially if the address is hosted by one of the big, free inbox providers, like Gmail or AOL.

Persistent attempts to send to full mailboxes can damage your sender reputation. The thinking goes something like this: if the sender continues to send to the same full mailboxes month after month, they may not be particularly careful with other aspects of their lists. ISPs know that even confirmed opt-in lists run into full mailboxes – it happens all the time. But they also know that senders with weaker permission run into the problem more often. Either way, the longer an address continues to bounce “mailbox full”, the less likely it is to become deliverable again, and it should be suppressed.

Senders can be somewhat less aggressive in suppressing full mailboxes at smaller receiving domains, like corporate e-mail accounts. Lots of corporate IT administrators aren’t as diligent about deactivating the mailboxes of former employees as senders would like, and there’s usually no reputation damage associated with them. From a ROI perspective, though, if you think a particular “full mailbox” should really be a “user not found” because the employee has moved on, it’s a good idea to suppress it.

That wraps it up for today’s questions. During the webinar, we touched briefly on what the law requires of senders. There have been some significant developments on the e-mail legal front since then, and in our next installment, we’ll take a deeper look.

Canada Passes The Ten Million Dollar Spam Law

Thursday, December 16th, 2010

Earlier this fall, we alerted our readers to the imminent passage of Canada’s strict new electronic messaging bill. On Tuesday, the Canadian Senate voted to adopt the legislation, and it was enacted by Royal Assent yesterday.

Our neighbors to the north may be the last of the G8 countries to adopt an anti-spam law, but it is the very strictest, creating penalties of up to 10-million Canadian dollars (or just under 9.87-million U.S. dollars) for businesses who send spam into or within Canada.

The new law, dubbed the “Fighting Internet and Wireless Spam Act” (or “FISA”, for short) imposes new requirements on senders of just about every type of electronic messaging, including mandates that stretch well-past the minimal requirements for e-mail under the U.S. CAN SPAM Act of 2003.

Under CAN SPAM, senders are required to abide by a series of labelling requirements, provide a working unsubscribe mechanism, and honor unsubscribe requests within ten business days. CAN SPAM, however, has never required that senders obtain prior consent from recipients. FISA requires either explicit permission, or implicit permission in the form of an existing business relationship or a conspicuous publication of the recipient e-mail address. If the publication of the address is accompanied by an instruction not to send unsolicited e-mail, it doesn’t count as implicit permission.

FISA creates a two-year window from the date an address was collected with implicit permission to try and convert it to explicit permission. If after two years explicit permission is not obtained, the sender must suppress the address. Both CAN SPAM and FISA explicitly preclude sending to addresses that have been automatically “harvested” from web sites.

CAN SPAM grants enforcement powers to the FTC, and gives ISPs the right to bring action against infringing senders themselves. FISA, in contrast, provides no criminal penalties, but allows both ISPs and individual recipients of spam to pursue civil action against senders.

The requirements seem to create significant new hurdles for senders, but authors of the Canadian law insist that the legislation is aimed squarely at only the worst of the worst offenders. FISA includes a “due diligence defense”, in which senders should not be held liable for violations if they can show they were making reasonable efforts to abide by the law when the offense was committed. Honest mistakes won’t count against senders.

Should U.S. senders be worried about the new Canadian law? Obviously, the law doesn’t apply if you’re not sending to recipients in Canada, but senders may not always know where (geopolitically speaking) the owner of a particular address receives their mail. However, if you’re already abiding by CAN SPAM and best common practices, you’re likely already in compliance.

The short answer is that (in theory at least) FISA is enforceable in the US, though the process is neither simple nor cheap. It takes about as much time and and money to obtain a judgement in Canada as it does in the U.S., so enforcement action is likely to be as rare, and therefore reserved only for the most egregious of offenders.

Canadian plaintiffs would also have to find a U.S. court willing to enforce the judgement, which is by no means a given. However, there is an open pledge between the U.S. and Canadian governments to support law enforcement efforts across borders. Earlier this year, for example, a Canadian court was willing to enforce a judgement obtained by Facebook in a California court against a Canadian spammer who racked up $873-million in fines for CAN SPAM violations. It will be instructive to see whether U.S. courts will be willing to reciprocate once FISA is enacted.

Within the e-mail community, the new law is regarded as further evidence of a trend in which legal requirements and best practices appear to be converging, albeit at a glacial pace. The take-away for senders, then, should sound familiar: adhere to CAN SPAM and best sender practices. Send to those who have granted permission, and try to engage with and obtain permission from any segments for whom you do not have it.
