# FormSMTP

> FormSMTP is an email API and form backend for static websites that sends through the user's own SMTP account (Gmail, Google Workspace, Outlook, Zoho, Amazon SES, Brevo, Resend, Mailgun or any SMTP server). No backend is needed: a plain HTML form or one fetch() call sends email.

- Free plan: 1,000 emails/month, 3 projects. Limited-time offer: the first 2,000 accounts get 10,000 emails/month free for their first 12 months (founding members).
