For a mailing campaign, one usually first selects the targeted recipients by their customer status. Mailings are always based on mailing lists. You can, for example, collect all customers who acquired a particular product in such a list. After passing the recipient data of those customers via a serial email to the external email system, the mailing as a whole can be created and edited there.
After the mailing has been dispatched, its success can be assessed in detail in the CRM, based on the recipients’ responses. This allows you to contact all customers specifically who, for example, wish to be called back. Since a mailing is linked to the history of every recipient, it is possible to retroactively trace which contact received which email and how they reacted.
