Matching against the negative list will take place within various processes and operations. This will ensure that no recipient on the negative list will receive your mail.

Before start of delivery, the assigned target group is automatically checked for unsubscribes and hardbounces. 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 negative list. If this is the case, the opt-in mail is not sent.

If you import a target group via the menu item Target Groups > Import, a matching with the blacklist takes place during the import process. In the history of the imported target groups, you can see whether or how many addresses against the blacklist have been filtered out.

If you import a target group automatically, a comparision against the negative list will take place. If the automatic import process generates a new target group, you can see the logfile of comparision in the target group history. When this process is matching the addresses into an auto target group, the information is also available in the history of that target group.

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

A target group (except for auto target groups) can be reduced for the blacklist entries by clicking the button “Reduce Target Group” (explicit: Unsubscriber, Hardbounces).

For each filtering of a target group using the personal data filter, a comparision against the blacklist takes place.
