# Messengers

Available since version `1.26.0`

Messengers are used to send messages from within FusionAuth to other systems.

### Message Types[#](#message-types)

Beginning in version `1.65.0`, each messenger can be configured with one or more message types in **messageTypes**. This tells FusionAuth which workflows the messenger may be assigned to.

For example, when configuring SMS or Voice settings in [multi-factor configuration](/docs/lifecycle/authenticate-users/multi-factor-authentication#tenant-mfa-settings-enable-methods-policies-templates) on a tenant, you can assign a messenger that supports the corresponding message type.

The legacy **transport** field remains for backward compatibility, but it is deprecated.

## Set Up a Messenger[#](#set-up-a-messenger)

In FusionAuth, you can set up three types of messengers:

*   [Set Up a Generic Messenger](/docs/customize/email-and-messages/generic-messenger)
*   [Set Up a Twilio Messenger](/docs/customize/email-and-messages/twilio-messenger)

To configure a messenger, navigate to Settings -> Messengers and click on the appropriate messenger type in the top right.

## Create a Messenger Template[#](#create-a-messenger-template)

Message templates are a powerful way to customize messengers and the communication contained within. FusionAuth uses FreeMarker for all templating.

*   [Manage Message Templates](/docs/customize/email-and-messages/message-templates)

To configure a message template, navigate to Customizations -> Message Templates .
