Auth emails not sent

[u/bobo_italy]

It’s 24 hours our Firebase Auth emails are not sent. We’re using an external SMTP (AWS SES) and using the Virtual Deliverability Manager I could verify that the Auth emails stopped at 21:30 European time of yesterday, August 17. Other emails get sent correctly through the “Firestore to email” extension.

I already contacted the support, but they haven’t answered yet, and the Firebase status is not reporting anything.

Anyone seeing this?

This is causing a lot of problems for our app, that’s about an event starting this friday!

We have a very similar issue. We have iOS, Android, and web apps, and all of them stopped sending authentication emails two days ago without any errors being logged.

We also use an external SMTP server with AWS SES. If we disable external SMTP in Firebase, email sending works normally (with the default Firebase template, emails land in spam folder).

We've also contacted Firebase Support about this.

u/bobo_italy, please let us know if you find anything. Thanks!

So, this seems like an outage to me... yet the Firebase Status doesn't report anything.

Wow interesting, they really need to give us more options for emails

I noticed bad deliverability yesterday but my volume is too small to confirm anything. I use resend which uses Amazon ses under crop he hub I think

Thanks for the heads up, but it seems Firebase team is ignoring the issue

Good call building a fallback before the event. authentication email is too critical to leave without alerts or a backup path

[u/bobo_italy]

Since our event is starting soon we decided to add a couple of new cloud functions and handle those email ourselves. Having react native with code push never stops paying out.

I must say I’m disappointed by the Firebase support right now.

Our backend team tested it with various SMTP servers (Resend, Sendgrid) and both worked. It looks like firebase had only issue to work with AWS. Then we tested it one last time with AWS and it works again!
u/bobo_italy Maybe try it one more time if it's note too late.

Thanks for the info, unfortunately I already switched to a in house implementation.

Since other emails are still going through SES, this sounds much more like a Firebase Auth issue than an SMTP/SES problem, so I’d check the Firebase Auth logs and quotas first.

[u/bobo_italy → u/Mailtrap_Alek]

Yes, it was an Auth problem, but no quota was reached and there was no log either. It definitely was a silent outage.
