How do I get started with A/B Testing?

NOTE: You must be on our Pro plan for this feature.


A/B testing is a powerful way to test variations of your campaign to see what works better. Typically only an "A" and a "B" segment are used, but you can create up to 5 variations of a single campaign. The recipients you add to your campaign will be more or less evenly assigned to the segments of your campaign.

Create segment "A"

Set up the messages in your campaign just like you've always done. Then click the "A/B Test" button:

Create segment "B"

Most of the time when you create your second segment, you'll want to copy everything you set up in segment "A" so you can make a few tweaks. If you'd rather just start with a blank canvas that's perfectly fine as well!

Now you can test out some variations from segment A. You can test anything, including:

  • Different subject lines
  • New follow-ups
  • Different gaps between follow-ups
  • Messages that go out on clicked links

View results

Once your campaign has been sent, the campaign overview will be broken down by segment. View stats for each segment on the "Summary" or "Timeline" tabs by clicking the various segments in your campaign.

View recipients by segment

On the "Recipients" tab there's a new "Segment" column in the list which you can filter by.

Exports contain segment data

And finally, Mailshake's  campaign exports include a new "Segment" column so you can easily use spreadsheet software to analyze performance.
