Postalytics is fully automated and acts very similar to email. A good rule of thumb is that once you hit send, it’s gone. It’s important to be sure your creative has been reviewed and approved and that there are no errors in the Campaign before it is finalized and sent.
There is approximately a 30 minute window in which Postalytics can call back a Campaign, however, this must be requested within the allotted time frame and we must have availability to do so.
