Compare email versions

Put up to four versions of the same email side by side and see how each one lands before it’s opened: the notification, the inbox, and the words they actually read.

How to compare versions

  1. On the email preview page, write your first version.
  2. Press Copy, then change the subject line or the opening.
  3. Come back here and pick the versions you want side by side.

If two versions read the same in the inbox, the open rate can’t tell them apart. Only what changes before the cut-off can make a difference to who opens.
