Email subject line tips

I came across some great tips on crafting the best email subject lines on the Litmus blog here. Of course, testing testing testing is the best way to get good results with any email campaign, but starting with these ideas is a good way to begin the tests from a good place.

And I’m always struggling with subject line length, and found the open rate vs. email subject line length to be cool:

“Subject line lengths and their corresponding open and click rates:

  • 4–15 characters: 15.2% open; 3.1% click
  • 16–27 characters: 11.6% open; 3.8% click
  • 28–39 characters: 12.2% open; 4% click
  • 40–50 characters: 11.9% open; 2.8% click
  • 51+ characters: 10.4% open; 1.8% click”
