A/B test your messages

Split a step into Variant A and Variant B. Hollerly sends each to half your leads and picks the winner by reply rate after 30 sends each. Here's how.

Updated October 3, 2026

A/B tests are on Pro and Agency.

Set up a test

  1. Open the campaign editor and click Edit message on a step.
  2. Turn on A/B test.
  3. Write or direct Variant A and Variant B. Half your leads get each one.

Each lead always gets the same variant, so follow-ups stay consistent.

How the winner is picked

  • Both variants need at least 30 sends before Hollerly calls it.
  • It compares reply rates with a standard statistical test at about 90% confidence.
  • Once a winner is clear, Hollerly switches everyone to it automatically on active campaigns. It checks once a day.

Watch and decide yourself

The A/B tests section on the campaign page shows each variant's sends, replies and reply rate, with a badge such as "variant A won", "B is ahead" or "collecting data". You can decide early with Use A for everyone or Use B for everyone, or click Keep testing.

Tips

  • Test one thing at a time, such as the opening line or the call to action.
  • Small campaigns may never reach 30 sends per variant. Test on a list of at least 100 leads.
