To cancel a scheduled split sendout.

- or -

To cancel a main sendout that takes place after a split message sendout. The split message sendout has already taken place.

Background Information​

In a split sendout, multiple versions of a draft email message are sent to a portion of your total recipient list in order to identify the highest-performing version. For more information, see Split Sendouts.

It is possible to cancel the sendout of a scheduled split test either

  • before any split messages are sent or

  • after the split messages are sent but before the main sendout is sent.

By canceling (as opposed to deleting) the split sendout, message statistics for sent split messages are retained in the system.

Once canceled, neither the split message sendout nor the split main sendout can be rescheduled or restarted.


  • Two or more message variations have been used to set up a split sendout test (see Test Multiple Email Message Variants (A/B Test)​). The time and date for the split sendout have been scheduled.

  • You hold the permission for message scheduling (Permission ​618: Campaigns: Schedule message sendout​).


  1. In the main navigation menu, click Message > Outbox > Email. The ​Processed Messages Overview​ window opens. The split sendout messages are identified with the label Split Test in the Type column.

  2. Next to any of the message variations scheduled to be included in the split test, click the filter symbol . The outbox is filtered and displays all versions that are a part of the planned split test.

  3. Click ​Cancel Split Sendout.

    • If the split messages have not been sent, the split sendout is canceled and will not occur at the scheduled time. If the split messages have been sent but not the main sendout, the main sendout is canceled. Message statistics for sent split messages are retained in the system.

    • The status for the split message on the ​Processed Messages Overview​ window is shown as ​Cancelled.

    • The draft messages included in the canceled split sendout remain stored in Mapp Engage. The messages can be viewed and edited in the ​Draft Messages Overview window. They can still be used for future sendouts (split sendouts or normal sendout).
