Email Subject Line Tester Tool


Even if you’ve created a campaign that includes the best email content that’s ever existed, if your target audience doesn’t click through to it they’ll never see it.

As such, it makes sense that the element which has the opportunity to gauge their interest and make them click through – the email subject line) is without a doubt the most important of all.

First and foremost is the word count. If your word count is above 6, you’re risking that it gets cut off by the recipients’ email clients. Data also suggest that if the word count is below 4, this can also have a negative effect on open rates. Keep the word count between 4-6 words for optimal performance.

Next is the character count. Data shows that a character count between 21-40 sees better open rates, so make sure to stick to that.

Your word choice is also essential. Using spam words is a big no-no of course, but in addition to avoiding spam words you also want a succinct word mixture and balance creativity with the point you want to get across. This also includes the preheader text. Be sure to test subject lines before sending with the best of all email subject line testers found at the top of this page!

Finally, the subject line type you opt for will depend on your marketing strategy and the goals of your campaign. The Advanced Marketing Institute has a headline analyzer, a simple tool which can show you the emotional marketing value of your email subject line. Type directly into the field and hit the ‘Submit for analysis’ button.
