====== When does blacklist matching take place? ======

Matching against the blacklist will take place during various processes and operations. It ensures that no recipient on the blacklist will receive mailings from your client.

===== Automatic matching before delivery =====

Before the start of delivery, the assigned target group is automatically checked for unsubscribes and hard bounces. Affected addresses are excluded from the delivery process.

Before sending an opt-in mail to a new address, it is automatically checked whether the recipient's address is on the blacklist. If this is the case, the opt-in mail will not be sent.

===== Import of addresses =====

==== Manual import ====

If you import addresses via //Addresses > Lists// and then click on the button and choose //Import addresses//, a comparison will automatically take place during the upload process. In a target group’s log file you can see which addresses were filtered out because of the matching.

==== Automatic import of ====

If you import addresses automatically, a comparison with the blacklist will take place at the same time. If the automatic import process generates a new target group, the log file of the matching can be seen in the target group details, just as in a manual import. When this process is putting the addresses into an auto target group successfully, the information is also available in the history of that target group.

===== Cleanup of target groups =====

==== Automatic daily cleanup of auto target groups ====

Auto target groups are checked for addresses on the blacklist on a daily basis. The unsubscribers in an auto target group can also be viewed in the target group statistics.

==== Manual cleanup of target groups ====

A target group (except for auto target groups) can be adjusted for blacklist entries by clicking the button //Clean up// (explicit: Unsubscriber, Hardbounces).
