Transactional Email

To enable transactional emails in your deployment, set the following environment variables. We recommend using Resend, 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

Variable	Description
SMTP_CONNECTION_URL	SMTP server connection (smtp://[user[:password]@]host[:port])
EMAIL_FROM_ADDRESS	The sender’s email address

You can also provide the SMTP connection details as individual environment variables instead of a full URL.

Variable	Description
SMTP_HOST	The hostname of the SMTP server
SMTP_PORT	The port of the SMTP server
SMTP_USERNAME	The username for SMTP authentication
SMTP_PASSWORD	The password for SMTP authentication
EMAIL_FROM_ADDRESS	The sender’s email address

If SMTP_CONNECTION_URL is set, it takes precedence over the individual variables.
