Auto target groups can be created manually or are created automatically when you create a newsletter or a block list.

An auto-target group is always up to date and therefore constantly changes in size due to:

• the subscriptions and unsubscriptions within a newsletter
• the nightly cleanup of negative list entries and hard bounces
• registrations generated via an address interface
• automatic imports (via an interface to an external CRM system or an automated import of addresses that were made available via SFTP)
• an upload of addresses to the SFTP server
• adding target groups or filtered addresses to an auto-target group
• manual cleanup
• automatic calculations that can be set up by promio.net

Static target groups are target groups that, unlike auto-target groups, are not automatically cleaned up. They are also automatically deleted after they have been used for a mailing unless they have been made read-only.

Static target groups can be created by the following actions:

• Imports
• Copying target groups
• Creating reactant target groups
• Saving a filtered copy
• Splitting
• Matching with another client
