# Autoresponder

*Marketing*. A system that generates email responses to actions and events.

An [autoresponder][] generates a response to an email, request, or action.

* You can engage an [*email service provider*][email-service-provider] to manage the infrastructure and support.
* You can *install a service on your servers*. This trades control for the need for infrastructure and technical skill.

> \[!NOTE]

> To set up an autoresponder with Twilio SendGrid, use the [Inbound Parse Webhook][] and the [v3 Mail Send endpoint][].
