โœ“

Two real campaigns

Sends the same email body twice, once with subject A, once with subject B, both to your full list. Two live campaigns, not a hunch about which line sounds better.

โœ“

Open-rate winner

Waits 24-72 hours for opens to settle, then compares the open rate of each campaign and reports the subject line that more people opened.

โœ“

You get the full picture

Reports the winning subject with both campaign IDs and the time the result was evaluated, so you can see the numbers, not just the verdict.

โœ“

What you walk away with

The winning subject line, reported with both campaign IDs and the time the result was evaluated.

How it works

Under the feathers

What actually happens when this skill runs.

  1. 1
    Give it the two lines

    You name the test, pick your email platform, and hand it subject A and subject B. The email body is the same for both, only the subject changes, so the test measures the subject and nothing else.

  2. 2
    Send both to your list

    It sends two separate campaigns to your full list, one with subject A, one with subject B. Everyone on the list receives both emails, so each subject line gets a real send. It confirms this with you before anything goes out.

  3. 3
    Wait for opens to settle

    It waits 24 to 72 hours (24 by default) while open data comes in. Open rates need a day or two to be meaningful, so it holds off on calling it early.

  4. 4
    Compare and report the winner

    It compares the open rate of each campaign, picks the subject line that more people opened, and reports it back with both campaign IDs and the time the result was evaluated.

What founders ask before trying a/b subject tests.

By open rate. It sends both subject lines as separate campaigns to your full list, waits for the opens to come in, then compares the two and reports the subject line that more people opened.
