Blacklists prevent selected contacts from receiving any messages in Mapp Engage across email, SMS, push, and in-app channels.
You can add email addresses, domains, or phone numbers to block unwanted communication and comply with privacy and regulatory requirements.
Key Points
System blacklist: Permanently removes the contact profile from your system.
Group blacklist: Removes only group-specific data; the profile remains in your system.
In both cases, the contact cannot be re-imported or re-subscribed using the same address or number.
Why use blacklists?
Ensure opted-out contacts no longer receive messages.
Prevent resubscription or re-import.
Stay compliant with privacy rules.
Keep your database clean of invalid or unwanted addresses.
Warning: A system blacklist deletes all contact profile data permanently.
