How to Use the Email Subject Line Tester

With the built-in Email Subject Line Tester, planning emails inside of your calendar just got that much easier. Write email subject lines that drive more opens, more clicks, and more conversions.


Check if Your Email Marketing Project is Set Up Properly:

  1. Go to Settings.
  2. Click on Project Types.
  3. Email Marketing or MailChimp should be listed here.
  4. If not, add it by selecting Add New Project Type.
  5. Once added, click on Email Marketing.
  6. Make sure the default attachment is Email Marketing.

If the default attachment is not Email Marketing, you will not be able to test your subject lines.

  1. Create a new MailChimp project or Email Marketing project on your calendar.
  2. Once your project is created you can type your subject line in the text box.

    • Words That Increase Opens

    • Characters, Words, & Emojis.
    • Numbers Present
  4. At any time, click Full Analysis to view a full breakdown of your subject line.
