Shared SMTP service has low deliverability for some users
Update - A fix has been deployed, all new projects are now fully operational. We're currently backporting the fix to affected projects (30% complete).

An immediate workaround is to use custom SMTP.

Unresolved incident: Shared SMTP service has low deliverability for some users.

No incidents reported.

Shared SMTP service has low deliverability
Resolved - We worked with our email provider to restore the shared SMTP service, and email delivery has now fully returned to normal.

All emails are being delivered as expected. We’ll be following up internally to implement preventative measures to reduce the likelihood of this happening again.
Dec 22, 07:57 UTC
Update - We are continuing to work on a solution for this issue. 



To clarify the impact: This only affects the shared SMTP service, which is intended for testing use only.



The team is, in parallel, continuing to work with our mail provider and is preparing a migration to a different service - we will go with whichever solution happens the earliest; however, this migration must be done carefully to avoid further issues.


If you need email services working immediately, you can still work around this immediately by following best practice for production use cases and configure custom SMTP: https://supabase.com/docs/guides/auth/auth-smtp

We expect to have an update no later than December 22 at 0900 UTC; however, we will share more information if it becomes available earlier.

Update - We are working with the email provider for shared SMTP services.

For now, users without Custom SMTP will continue to see email deliverability issues for auth-related emails.

We are also exploring other provider options in the event we need to migrate in the near term.

Identified - We have identified the issues with sending mail via the shared SMTP service and are working on a fix.

For any production workloads, we would still strongly encourage setting up custom SMTP on your projects. More information available on configuring that here: https://supabase.com/docs/guides/auth/auth-smtp
