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