Top Five Email Subject Line Testers You Should Try

After generating your subject lines, you need to test their open rate before sending them. The subject line tester determines the open rate of your email.

Here are the top five email subject line testers you should try:

1. Co-schedule

Coschedule’s email subject line tester uses a 100-point system to assess subject lines. Word count and reading level play a huge factor to score level. The scores increase when the subject line is simple to read and grasp.

It also scans for spam-filter-friendly terms like ‘Free,’ ‘Re:,’ and so forth. Coschedule flags them down, so your emails aren’t marked as promotional by the email service provider (ESP).

The excessive use of punctuation, the correct use of capitalization, and personalization are all considered in its review.

Coschedule also allows you to check how your subject line will appear on a desktop computer and a smartphone.
