Supabase email rate limit

By Flavio Copes

How to fix the Supabase 'email rate limit exceeded' error when testing auth emails, by setting up your own SMTP server in the authentication settings.

I need to remember this, when testing Supabase, their SMTP servers block after a few emails (5? 10? 15? few, anyway), so after a while you’re trying things, email will stop working and it’ll start giving you an error message back:

Error: email rate limit exceeded

How to fix?

You need to use your SMTP server to go over that limit, in Settings → Authentication → SMTP Settings.
