Email

Configure SMTP so Plane can send login alerts, password resets, and other Cloud notifications from your deployment. If you do not already have an SMTP provider, services such as Resend, SendGrid, or Amazon SES can be used.

SMTP is optional. You can skip these variables if you do not need email notifications yet.

.env

EMAIL_PROVIDER=smtp
SMTP_HOST=
SMTP_PORT=587
SMTP_AUTH_USERNAME=
SMTP_AUTH_PASSWORD=
SMTP_TLS_MODE=auto
SMTP_SKIP_TLS_VERIFY=false

Environment variable	Description
`EMAIL_PROVIDER`	Email transport Plane should use. Set this to `smtp`, or leave it unset so Plane uses SMTP when `SMTP_HOST` is configured.
`SMTP_HOST`	Hostname of the SMTP server that sends mail for your deployment.
`SMTP_PORT`	Port your SMTP server listens on. Use the value required by your provider.
`SMTP_AUTH_USERNAME`	Username used for SMTP authentication. Some providers require a fixed username such as `resend`.
`SMTP_AUTH_PASSWORD`	Password or API key used for SMTP authentication. Store this as a secret.
`SMTP_TLS_MODE`	TLS mode Plane uses for the SMTP connection. Use `auto` for STARTTLS-capable servers unless your provider requires another supported mode.
`SMTP_SKIP_TLS_VERIFY`	Whether to skip TLS certificate verification. Use `false` in production.
