Before you can start sending with MXace you need to make sure you do the following:
The Sending Identity establishes who will be sending emails. This is a critical and mandatory piece because it helps establish and protects your domain reputation by ensuring others can’t use your identity to send email without your permission.
Your list consists of the email addresses you are sending. Your lists should be segmented into areas of matching interest.
A Campaign is what “controls” a list. This is a “how” you will schedule and send to a list a particular email message.
