How do I add a client to the newsletter?

To add a client to the newsletter, you will need to add them first as a client or as a subscriber.

Once added, you will then need to go to subscribers (Under the communications tab) and find them there.

Then on the rightmost tab where it says Actions. Click on that and it will give you a dropdown.

Click on Subscribe to subscribe them to the newsletter.
