# Follow-up

The follow-up campaigns are useful to automate the sending a sequence of emails based on a user action with a delay.

The follow-up is an AcyMailing feature that allows you to send a series of emails with specific delays when a user performs a predefined action.<br>

In this example, users that subscribe to the "Tips and tricks" AcyMailing list will receive 3 emails: one directly, one after a week and a final one after a month.
