Custom emails

Why aren’t magic links or confirmation emails sending?

Supabase’s default mailer only sends to pre-authorized addresses (your org team). To deliver magic links, sign-up confirmations, and password resets to all users—and to send from your own domain (e.g. no-reply@motivd.com)—you need custom SMTP.

Send branded emails from your domain

1. Choose an SMTP provider (Resend, SendGrid, Postmark, Brevo, AWS SES, etc.) and verify your domain (DNS: SPF, DKIM).
2. Create SMTP credentials in the provider and a From address on your domain (e.g. no-reply@motivd.com).
3. In Supabase Dashboard → your project → Authentication → SMTP Settings, enable Custom SMTP and enter host, port, user, password, sender email, and sender name.
4. In Authentication → Email Templates, paste the branded HTML from supabase/email-templates/ (or run node supabase/email-templates/apply-templates.mjs).
5. Set Site URL under Authentication → URL Configuration so links in emails point to your app.

Keep emails out of spam

• Use a brand name as Sender name (e.g. “Motivd”), not a person’s name. A personal name with an external domain can trigger Gmail’s “Be careful with this message” / impersonation warning.
• Verify your domain in the provider so SPF and DKIM are set. Add a DMARC record (Gmail and Yahoo expect it).
• Use a transactional From address on the same domain as your site (e.g. auth@ or notifications@). See project docs and Resend’s deliverability guide for more.
