A split-run test allows you to compare different designs or subject lines in a test mailing prior to the main delivery. In the main delivery, the best performing mailing is then automatically sent to the rest of the recipients. When creating the campaign, select the type A/B Test Campaign.

This box – which only becomes visible after setting up the creatives – contains all necessary settings for split testing.

• Target group: Unlike standard campaigns, split testing requires the target group to be selected at the campaign level. The target group contains the addresses for both test run and main delivery.
• Test Part of target group: The percentage of the target group that will be used for the test run.
• Duration test period: Defines the period of time between test run and main delivery in hours. In this time the winner gets identified.
• Winner Parameter: The message with the highest value in this category is declared A/B test winner. It can be determined on the basis of conversions, clicks or opens.

The delivery date that has been inserted under Actions > Send campaign > Delivery date refers to the start of the test part. The main delivery starts after finishing the test period.

Example:

• Duration test period: 5 h
• Campaign start: 10 o’clock

The test run starts at 10 o’clock, the main delivery follows at 15 o’clock.
