Should you maneuver certain “secret” words into your subject lines to get people to open email?
In a webinar called The Science of Email Marketing, analytics nerd Dan Zarella said bluntly, “I would rather have an email subscriber than a Twitter follower.” We’d like to think it’s because email subscribers respond better to promotions, but according to Dan’s presentation, email and Twitter are almost equal in terms of lead generation. Still, our Twitter followers are often fair weather friends, aren’t they?
Dan reminded businesses that 88% of people use their work email as their main email address, so your email subject lines can’t be boring. ”You’re competing with baby pictures and invitations to dinner,” he said.
Boring, jargon-y words like evaluation, soon, administration, liked, please, minutes and enjoyed were the most common in top unopened emails.
Dan pulled Hubspot’s data from over 500,000 emails sent, and the top seven words with the best open rates tended to indicate a benefit to the user:
Dan commented on these results, saying to “phrase it in a way for what I as the reader wants”.
Still, you can’t listen to what just one test says, in fact you should really be looking at your own data for this information. Mailchimp, however, also had its own set of popular words coming from an even bigger dataset of over 9.5 billion emails. Here were the top seven:
Like Hubspot’s data, these words show that telling users what’s in the email is a good thing. It also tells you that digests, or week-in-review type email seems to be working really well too.
But what about bad words to use in subject lines?
Vertical Response had some tips that may or may not set off official spam filters, but they tend to set off human filters:
- Don’t write subject lines ALL IN CAPS.
- Don’t make spelling mistakes.
- Don’t plea with people to “Open Me!”
- Don’t deceive readers with a false promise.
- Don’t give away everything in your subject line.
- Don’t use one word – like “Hi!” – as your subject line.
- Nix the punctuation!!!
- Don’t add Re: to your subject line to deceive readers.
MailChimp also identified three words that won’t trip the spam filter, but still get low open rates due to being deemed spammy by readers: Help, Percent Off, and Reminder. Interestingly, they also found personalization doesn’t increase open rates, but locality does.
One of the easiest ways to get double duty from your email subject lines is to start with a great idea based on one of our proven Email Subject Line Archetypes and combine it with the List subject line. List subject lines that work are often something along the lines of “8 rabbit breeds to love” or “10 things you need to know about raisins.”
In fact, our friend Stuart Hochwert at Prime Publishing, who has multiple cooking and crafting online communities, uses List subject lines almost exclusively. He tells us he’s tried others, but the numbers almost always win. He admits his 20-odd editors get really, really bored writing the same kind of subject lines all the time, but he keeps them in line well enough to consistently earn open rates ranging from 10% to 20%.
Here’s a typical subject line that scored an 18.2% open rate:

How can you top that? Well, whether the writer knew it or not, here’s an even better email subject line that combines the number with an implied benefit – and, if you’ve been following Mequoda at all, you know that benefits are the single most powerful tool a copywriter can deploy.

Shazam! A list and the benefit of easy meal preparation! That one zoomed to a 19.6% open rate, and that’s what I call a subject line that works!
