**Your software** My Mautic version is: 4.0.0 My PHP version is: 4.7.33 My Database type and version is: MariaDB **Your problem** My problem is: I wanted to learn about the “Do not contact” event thats triggered on contacts who unsubscribe. If that contact is part of a Segment, next time when I launch a campaign for that segment, will Mautic detect and not send the emails to these contacts? This is the first time I am using this so wanted to make sure I am not sending emails to those who have unsubscribed. Thanks These errors are showing in the log: Steps I have tried to fix the problem: ---

Yes once a contact is marked as DNC they will no longer receive an email from the system, neither from a segment email or a campaign email. ---
