Both SubscriberMail and Blue Sky Factory recently released lists of words that shouldn't be used in emails because they're likely to trigger spam filters. But I see some of these words—like "free" and "discount"—used routinely in the subject lines of commercial email that I receive. If I have a good reputation do I need to worry about content filters? Am I staying away from these words unnecessarily? —S.G.

The Voices of Email had this advice:

J.F. Sullivan: The answer should be no. If you have a good reputation then you do not need to worry about content filters. The actual answer is another question, as in it depends on two things: What's your definition of a good reputation, and which content filter are we talking about?

Everyone in the email marketing (and message security) ecosystem has a different view of what a good reputation actually means. For some it's as simple as making sure they are not on a blocklist; for others it may be that they are in compliance with a specific Sender Authentication implementation. In order to answer "yes" to the question, it may be more useful to provide a checklist summary of what a good reputation constitutes. So, if you can say "yes" to the following reputation aspects:

1. You have a good public reputation (not on blocklists, or have upset any ISPs).
2. You have good legislative adherence (e.g., CAN-SPAM compliance).
3. You have good infrastructure (e.g., DNS, MX records and the like).
4. You have good identity (e.g., you have a correctly configured SenderID record).
5. You have best practices (e.g., list scrubbing, opt-in, etc.).

…then yes, you do have a good reputation so you will not need to worry too much about content filters. And while your good reputation will work, say, 80% of the time, your actual delivery will still depend on the content filter you encounter to some degree. A subject of much longer blog entry for another day…

Rob Fitzgerald: You always need to be aware that filtering exists, but I don't think you need to be ruled by that existence either. It's interesting to lay out all the various releases, of all the various words that shouldn't be used within in an email, and see how incredibly long that list is. Sometimes it makes me wonder how you can actually put a string of sentences together without actually using any of them. Practically speaking, you have to use some words that may be "known" filter words. I don't think that should give you pause to run the campaign for fear of a lack of response. We've sent out many campaigns with the word "Free" on them that have performed very well.

I tend to look at it this way—it's all about moderation. Put together a creative with a lot of words that trigger filtering and it could be adversely affected. Give that same creative a diet, and keep some of those same words included, but not all of them, and I think you'll be OK.

Stephanie Miller: Despite the frequency that I receive this question, there is still no magical list of words to avoid, nor is the use of marketing terms like "free," "discount," "special offer" and "click here" an automatic block. Don't misunderstand. Those words can get you blocked. However, judicious, responsible and clear use of them usually won't.

Why? Because spam filters dynamically update to reflect current market conditions and spammer behavior. The only way to ensure your content does not depress inbox deliverability is to run every email through a series of popular message filters to determine your spam score before sending to your entire mailing list. You can do this through a service or on your own by setting up multiple accounts at different ISPs.

Here's how to optimize your message for response and deliverability: Write the copy as a marketer. Sell. Build the relationship. Clarify the offer. Make the call to action very clear. Then, test it. If you fail the spam filters, adjust it. Before you hit send, even if you pass the filter test, be sure to give your message AND subject line a "smell test." If your readers or subscribers will think it's spammy, so will the receivers. If you are using all capped, repetitive words that filters watch like "FREE SHIPPING THAT'S FREE" or using strange punctuation like ***NOW ON SALE***, then you are likely to be blocked.

Chad White: Inspired by this question, I did a little real world research and found that major online retailers have used many of the "dirty" words on SubscriberMail's list of words to avoid using in subject lines. How many have they used? They've used 27 of the 100 in the past two months alone. Some of the words—like "Free," "FREE," "Offer" and "Buy"—they used a LOT. So it's clearly possible to use these no-no words in subject lines under the right conditions. Based on that I'd say that you should explore using them but test to make sure your emails are getting through.

Bulldog Solutions hosted a live roundtable on Email Deliverability for BtoB Lead Generation earlier this week. We expected a great turnout for this Webinar—and we weren't disappointed. More than 50% of registrants made time to attend the hourlong live event—an attendance rate that exceeds nearly every measure for online marketing we track in the Bulldog Index.

Our panel included two familiar EEC names: Stephanie Miller of Return Path, who is the EEC's vice chair for member initiatives, and Michelle Eichner of Pivotal Veracity, who leads the EEC's deliverability and rendering roundtable. That group produced the March report on email standards and bounce management that we referred to several times during the webinar. We also had Ryan Rutan, a senior programming analyst at National Instruments, who offered his perspective from an organization that's confronted many of the issues marketers are facing. You can view a recording of the roundtable here.

Prior to the webinar we solicited questions from our registrants, a practice we typically employ to help us ensure the panel addresses the audience's biggest pain points. As the EEC's Jeanniey Mullen pointed out, the questions themselves are fantastic market research.

Here's one observation I think we can all relate to. The questions showed us that marketers want a magic bullet. This is human nature and not surprising, but when the topic is complex, it's not always easy to provide. While they're certainly willing to put in the work on testing and research, and to consider variables such as industry and message, the fact remains we received many questions asking for answers on:
—The best time to send emails
—The most successful subject line
—The best word count for a promotional email
—A definitive answer on whether text or HTML is best

One attendee summed up the panelists' responses with humor: "Great stuff. Very knowledgeable panel. Bottom line: It depends. Ha ha."

During the webinar we promised attendees we'd answer some of the questions we didn't get to address during the live event. We'll use this blog and Bulldog's sales and marketing blog, as well as our Marketing Watchdog Journal newsletter, to communicate when we have some Q&A written up for the audience to explore.

Fellow eec blogger Chip House recently blogged some good points on email marketing sustainability in response Michael Specter's recent article, "Damn Spam" in the New Yorker .

As Chip notes, Specter's piece is a fascinating piece of historical reporting on the origin of spam. Too bad Specter misses the whole point of how the spam problem is being tackled today—and how, I believe, it will eventually be solved.

It's really challenging, both from an intellectual as well as corporate resources standpoint—for receivers of all stripes—ISPs, universities, corporations, etc- to keep up with the spammers. Spam evolves. Specter reports, "Indeed, most anti-spam techniques so far have been like pesticides that do nothing other than create a more resistant strain of bugs."

Return Path responded to the article by correcting Specter's suggestion that using reputation analysis (i.e., Is this sender good or bad?) is susceptible to gaming by spammers in the same way that content filters (i.e., does this email look or read like spam?) are today. We also blogged about it here.

Our response was written by Return Path CEO Matt Blumberg and GM of Deliverability Solutions George Bilbrey. Since they are a lot smarter than I am, I quote their letter in part:

"In fact, reputation metrics, if used well, are impossible to fake for more than 24 hours. A server that sends email that garners lots of complaints from recipients cannot make those complaints disappear. A server that has a spammy configuration (like open proxies or open relays) can't fake those technical settings. Spammers can, and do, switch servers and IP addresses, but these "no reputation" IPs are viewed with suspicion by receivers until they accumulate enough data on them to develop a reputation.

Even if they spend time up front establishing a good reputation by using good sending practices, no true spammer can ever get or keep a good reputation—a standard that is increasingly becoming the only path to inbox placement. But, legitimate email marketers—retailers, publishers, non-profits and others—can establish good reputations that make sure that consumers get the email they sign up for and want to receive. Reputation systems offer the best of both worlds—a decrease in unwanted email and a decrease in false positives. For this reason, more and more internet service providers and corporate email administrators are moving to reputation systems to stem the spam tide. While spam may never completely end, the improvement of these systems will surely have many spammers looking for a new line of work."

Please let me know your thoughts on the article, and what role you believe sender reputation plays in reaching the inbox today—and tomorrow.

We create shopping/advertising websites for media companies. People who register at the sites are invited to receive emails with special offers from the site. We start emailing each list after about 100 members sign up, but prior to hitting that threshold the only other email they would have received from the site is the confirmation email. I have been looking all over for some info on "starting from scratch"—a how-to or best practices for that initial email. Do the Voices of Email have any advice? —L.S.

The Voices of Email had this advice:

Rob Fitzgerald: Start the mental and marketing integration of your brand in that message—have it in the "from" line, the subject line, and in the email itself. Successful email marketing blossoms from consistency of message and consistency of branding. Also, be clear on the "what comes next," what types of email offers will you be sending. Leave no chance for misunderstanding and your registrants will appreciate that. Be sure to present the person with the clear opportunity to opt-out from receiving any future emails from you. Lastly, don't wait too long to send out marketing emails from the time the initial confirmation went out. There should be some immediacy to it or you risk disconnecting your registrant from your initial value-add.

Stephanie Miller: This is a great opportunity to launch an email conversation with prospects in order to engage early and lead them through the sales cycle. In fact, a conversation strategy on email is perfectly aligned with the goals of a newly launched shopping website—build the file over time, build relationships, optimize the early growth and leverage for future market saturation.

Today, you are "holding back" on sending email messages until you reach a critical mass of 100, and thus penalizing folks who join the list early. Rather, you want to celebrate these folks and "wow" them so keep reading and even tell two friends about your newsletter. Instead of thinking about it like a traditional publisher (where everyone gets the same content on the same date), think about it like a short-term email conversation—every subscriber gets the same experience. Email message one comes on day one, regardless if you signed up on June 1st or July 31st.

Offer something of real value for signing up—e.g., a free report or coupon—and use an auto-responder system that allows you to send brief, topical newsletters on a regular basis. If you have already built the website, send that content out in bite-sized, well-constructed tidbits to keep subscribers engaged. This will minimize the work and equalize the experience across all subscribers.

Once you set up this "series" of emails, you can trigger it for all new subscribers, regardless of the day they sign up, or their position in the queue. Using the same series for each subscribers ensure that each has a similar (and optimal) experience.

After you learn from this email conversation, active buyers can be converted to a more traditional promotional email program, where everyone gets the same promotion on the same day. But using a conversation in the beginning ensures that you engage fully with new subscribers, and optimize sales across the board.

Good luck!

Jeanniey Mullen: I would start with a strong subject line that includes the company name and something that indicates these are message they requested. For example: XYZ: Site special offers now available. Or: XYZ is ready to bring you special insights

I would also focus on the copy reminding people that they asked for this info, and VERY clearly giving them an opportunity to opt out of this section only.

Hope that helps!

Chip House: We've found that the Welcome email may in fact have the most impact of any email you ever send your subscribers. Opens, clicks etc. all tend to be the highest for an initial email, then can drop off from there if you don't continue to engage your audience or follow-up on the promised content, education or offers promised when they opted in. My advice is to first put substantial effort into optimizing that email. Sure it is transactional in nature, but make sure you do things like:

- Reiterate what they can expect from you in terms of content and frequency.
- Ask them again to add your "from" address to their address books to "ensure good deliverability and rendering."
- Don't forget to make it compelling. Using HTML is best. And don't be afraid to use the CAN-SPAM legitimized commercial content below the transactional introduction.

Getting off on the right foot will pave the way for your first set of campaigns. If you are speaking to their needs, no need to wait for a critical mass.

Chad White: Welcome emails are absolutely critical. Ideally, they not only quickly reassure subscribers that they are subscribed, but they also set the tone for the relationship and reinforce expectations that were (hopefully) established during the subscription process. Unfortunately, only about two-thirds of the retailers I track via RetailEmail.Blogspot use welcome emails, and then only a fraction use them well, missing the opportunity to promote their content, plug their services and tout unique and popular products. At the Email Insider Summit in May, Niti Chhabra, an email marketing consultant to BabyCenter, said: "Give them a reason to save the welcome email." If you don't feel like you're doing that, then you should sit down and makes some changes.

Almost as important as that welcome email are the few that follow it. With each email they're going to be asking themselves, "Was subscribing a mistake?" In some cases, you can increase your chances of keeping that new subscriber if you use an onboarding campaign, where you extend the introduction process. I just wrote a reportlet on onboarding emails that may help you, and in a few weeks I'll be releasing the sequel to last year's Retail Welcome Email Benchmark Study.
