A/B test your subject lines with new flexible durations directly in your Broadcast Email Editor. Choose from 30 to 240 minutes in 30-minute increments to find out which subject line resonates best with your readers.

This new feature gives you…

  • Flexible testing: Adjust the test duration from 30 minutes up to 4 hours to better suit your schedule and still get valuable insights.
  • Automatic deployment: Once a winning subject line is identified, it is automatically sent to the remaining recipients.
  • Real-time insights: Monitor your A/B test on the Broadcast → Analytics page to see the winning subject line, determined by the highest open rate.

This update makes it easier to improve your emails without changing how you work. There's no extra learning required—just more control for you. Try it out the next time you write your newsletter!
