I’m mailing a schedule to my contacts about once a week. I’ve created a new campaign with the htmlfetch at send with %EMAIL% so my app knows which contact’s schedule to render.
For certain contacts no appointments are found so I want to cancel the mail from sending to that specific contact.
Any idea how to accomplish this? I can throw a 500 error but then AC tries 10 times again resulting in over 100.000 requests.
