The principal is the company commissioning the newsletter. In the simplest case, this corresponds to the client in which a newsletter is dispatched. However, there are also more complex use cases that require additional principals.

Several principals come into play in the following cases:

One case is when you want to dispatch several newsletters which have to be managed separately. Reasons for this may be:

• separate processes for subscribing and unsubscribing
• a separate report is required
• different test delivery lists
• discrete billing or accounting

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

Use different clients when you send out newsletters for different customers and want to manage them separately. In this case, you can set up your customers as clients in the Account section in the same way as in the case above.

Via the account settings button on the top right you can go to Companies & Clients. Then select the tab which also says Companies & Clients. You can now create a new client with the button on the bottom right.
