A few tests to prove which subject lines make for great open rates
Studies show that most people decide whether to open and read an email message based entirely on a quick glance at the sender’s address and the email subject line.
If you’re an email newsletter publisher or marketer, you have four tasks: Get your offer delivered, opened, read and converted.
One of my favorite new tools to play around with is MailChimp’s subject line suggester. It’s only available if you have a MailChimp account, but you can get a free account on their website, so you might as well give it a test.
What this tool does is ask you to enter a few words into their tool. It then spits out how that combination of words has worked in the past. I decided to try this method on some of our favorite subject line archetypes.
The HOW-TO subject line
The how-to subject line is more specific because it promises to reveal “how-to” achieve the benefit. It is nearly impossible to write a bad how-to email subject line. Simply join a mouthwatering benefit to the words “how to.”
Winner: “how to make”
The FASCINATION Email Subject Line
Fascinations are compelling, benefit-driven bullet points that motivate the reader to discover the answer. Fascinations exploit the reader’s curiosity. Often, fascinations include the words “discover”, “secrets” and “amazing”.
Winner: “Discover the”
Surprisingly, further down the list in the one-star section was “10 Secrets”. Guess everyone’s over all those so-called “secrets.”
