What is the difference between a Newsletter and Autoresponder message?

Newsletters are one-time messages sent to chosen campaigns, segments or manually selected contacts. It is a great tool for letting your customers know about new offers, updates and promotions.

Autoresponders are messages set to go out automatically. They help you automate campaigns and manage one-to-one communication with your recipients. They are sent in a sequence at intervals calculated starting from the day a contact opts in to your campaign (e.g. Day 0, 3, 7, 14).
