Formbase sends emails for account verification, password resets, and optional submission notifications. You must configure an email transport in self-hosted environments. Choose one of the supported transports below.
1

SMTP configuration

SMTP_TRANSPORT=smtp
SMTP_HOST=smtp.mailgun.org
SMTP_PORT=587
SMTP_USER[email protected]
SMTP_PASS=your-password
SMTP_USER and SMTP_PASS must either both be set or both be empty.
2

Resend configuration

SMTP_TRANSPORT=resend
RESEND_API_KEY=re_xxx
Resend uses API key authentication and requires no SMTP host.
Use a dedicated sending domain for better deliverability and easier monitoring.
