Email handling

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_PORT=587
SMTP_AUTH_USERNAME=
SMTP_AUTH_PASSWORD=
SMTP_TLS_MODE=auto
SMTP_SKIP_TLS_VERIFY=false

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_PORTdefault 587

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_MODEdefault auto

TLS mode Plane uses for the SMTP connection. Use auto for STARTTLS-capable servers unless your provider requires another supported mode.

SMTP_SKIP_TLS_VERIFYdefault false

Whether to skip TLS certificate verification. Use false in production.
