Creating Great Subject Lines

by Emily Zabor | Nov 7, 2022

Have you ever sent an email that failed? You look at everything that could have caused this result – send time, frequency, spell checks, an incorrect merge tag, the subject line wording, etc. What if you had a tool that could help you improve your open rates and tell you if your subject line would perform well? 

Introducing your free email subject line tester: Send Check It

Send Check It gives you feedback on your subject line that has been compared to 100,000+ emails. Yes, you still need to write your own subject line, but with this tool, you won’t need to question if it is good or not. 

Why is a great subject line important? 

I like to think about a subject line like a first date. Your first impression matters. Are you easy to understand? Are you interesting? Did you arrive at the right time? Do you leave a little room for mystery or are you being a bit too clingy? It’s easy to kick someone to the curb if they aren’t consistently following through on these things. The same goes for your subject line. You have one opportunity to make a good impression or pique the interest of your email recipients. If it isn’t up to par, your email metrics will suffer, and your intended recipients may never see your message. 

What does Send Check It do that we can’t do on our own?

  • Gives an overall grade of the subject line: I recommend only sending if you get an ‘A’
  • Measures scannability: How easy it is to read? 
  • Measures reading grade level: A lower level generates more opens 
  • Shows if words in the subject line might trigger spam filters 
  • Measures length, spelling, & punctuation 
  • Includes suggestions for better open rates 

What should your next steps be? 

  • Educate your team with this tool and use it for EVERY email. 
  • If you don’t have a current email strategy, use this tool to start A/B testing emails with subject lines (personalization v. non-personalization, asking a question v. a statement, including an emoji, being descriptive v. broad). 
  • Track your open rates to see how your subject lines perform and work on re-creating which subject lines have worked well.
