Messages aren't sending — where to look

A checklist for the three most common delivery problems.

1
Check that the workflow is published, not saved as a draft.
2
Confirm your phone number registration is approved — unregistered numbers get filtered.
3
Verify email domain authentication; missing records send mail to spam or block it.
4
Look at the contact's communication preferences — an opted-out contact stops all messages.
