+## Deleting your users
+If you delete a user from your system, you should also delete them from Intercom lest they still receive messages.
+
+You can do this using the [intercom-ruby](https://github.com/intercom/intercom-ruby) gem. In the example below we're using an ActiveJob to perform the delete in the background.
+
+```
+class User
+  after_destroy { DeleteFromIntercom.perform_later(self)

+
+class DeleteFromIntercom < ApplicationJob
