Blocking deliveries without unsubscription link
Hi all,
I was wondering if there is a way to setup a typology rule for blocking deliveries without the unsubscription link. Unfortunately the default one only generates a warning when the opt-out link is missing, and there is no way for changing the level (from "warning" to "error") or for changing the code.
Did someone of you ever realized something similar?
Thanks in advance!
Simone
