It can be useful to create a newsletter for the following use cases:

Reasons for this could be
* a separate subscription and unsubscription procedure
* a separate report is required
* different test delivery lists
* separate billing

In this case, you can set up different customers and different departments of your company, for example, as clients under Account > Client Management via the button Create new client.

Reasons could be
* a separate report is required
* different test delivery lists
* separate billing

In this case, select your customer as the client in a campaign.

Under Addresses → Lists → Newsletter, you can create a new newsletter by clicking the button at the bottom right. A corresponding auto target group is automatically created for each newsletter.

Name your newsletter and select a client. You can also enter a short name, a description, which is then displayed by default as the description text on the newsletter administration page, and a customer code.

You can also check the boxes for activation and visibility.

When creating newsletters in omnichannel clients, you can define a daily automatic cleanup of addresses without channel opt-in.

If the newsletter is assigned to a channel, the associated auto target group is automatically cleansed of all addresses that do not have an opt-in in this channel. If All channels is selected, no automatic cleansing takes place.
