Mailrelay API Reference

Groups

Groups are the lists that your audience is segmented into, such as Customers or Newsletter.

A subscriber can belong to as many groups as you need.

Groups are the main way to decide who receives a campaign: you pick the groups that you want to send to and, optionally, the groups that should be excluded from that send.

Removing a group doesn't remove its subscribers. They remain in your account and keep any other group that they belong to.
