# DELETE an A/B Test for an Email Campaign Activity

`DELETE /emails/activities/{campaign_activity_id}/abtest`

Deletes an A/B Test on an primary email campaign activity. You can only delete A/B tests that have a `current_status` of `Draft`. Deleting an A/B tests reverts the email campaign activity `type` from A/B Test (code= `57`) back to NewsLetter (code= `10`). Constant Contact uses the original subject line, rather than the alternate A/B test subject line, when an A/B test is deleted.
