With the help of mailing (distribution) lists, you can easily collect external or internal contacts. When associating a mailing list with a marketing action or a correspondence, all accumulated contacts are added as a common distribution list. This saves you from having to assign numerous contacts individually. You can use mailing lists as often as you want.
You can create mailing lists in the marketing module (Marketing/Mailing lists).
In the Members tab of the mailing list, you can collect the relevant contacts. In the Activities, Sales and Marketing tabs, you can see the usage of the contacts. There, marketing actions can be assigned directly. Additionally, the form shows you the Activities and important Documents.
