# Transactional Email

To enable transactional emails in your deployment, set the following environment variables. We recommend using [Resend](https://resend.com/), but you can use any provider. Setting this enables you to:

* Send emails when new members are invited
* Send emails when organization join requests are created/accepted
* Log into the Sourcebot deployment using [email codes](/docs/configuration/auth/overview#email-codes)
