Review the result
Split-test statistics include sends, opens, clicks, unsubscribes, bounces, spam, logs, and exports. The winning-decision process runs separately from initial test preparation and sending.
Choosing a winning criterion
Use opens as the winning criterion when you are mainly testing subject lines or preview text, since open rate isolates the decision most people actually make first: whether to open the email at all.
Use clicks when you are testing body copy, layout, or the call to action, since click rate reflects how well the content itself performs once someone has already opened it.
Frequently asked questions
- How many campaign variants can a split test include?
- You can add multiple saved campaign variants to a single test; each is sent to its own slice of the decision-percentage audience before a winner is chosen.
- What is the decision percentage for?
- It sets how much of the total recipient list is used to evaluate the variants before K2Mailer determines a winner, leaving the remainder to receive the winning version.
- Can I stop a split test from auto-sending the winner?
- Yes. Configure the test to only show the result instead of sending the winner automatically, so you can review the outcome and send manually.
