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
- Open the campaign editor and click Edit message on a step.
- Turn on A/B test.
- 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.
