Newsletter - dedicated sending

Possibility to manually add a contact to the newsletter while editing customer data. An automatic mailing is then sent out asking for confirmation of the subscription and the customer is put into a network of contacts who are notified e.g.. about important events in the life of the company, promotions, etc. Contacts can be assigned to account groups, which has an impact on discounts, rebates, offers, mailing groups (whether and which message the customer receives)
