Why does it take 30-60 minutes to receive email verification message?

Hey,

Why does it take 30-60 minutes to receive email verification message on other emails than gmail? If I register user with gmail account the email comes straight a way, but if I use other email account than gmail it takes 30 to 60 minutes to get that verification message? Why is that?

I’m using sendEmailVerification() function to send that message after signup and after email is changed by the user.

There is also StackOverflow question on this topic from yesterday (not asked by me) but I figure here is better chance to get answer sooner. StackOverflow question

Completely agree with Simon Burbage.

I chose Firebase because it had a comprehensive set of back-end services in one place. I don’t have another mail server option in mind and want to use Firebase for this purpose.

Can we please have a “proper fix”. If all that is needed is a working mail service it seems odd that this is taking so long.

Thanks

Adam

@kmcnellis https://github.com/kmcnellis Thanks for letting us know about this. Whilst it is great to have this as an option for those who need/want the customisation, it seems a real pity that we would have to use our own servers (or another service) when a lot of the reason why we’re using Firebase is to avoid that. Also, the fact that we might be successful using another mail delivery service whereas Firebase are not is a little odd and disconcerting. I hope this is therefore not seen as “the answer” to the problem when surely that should be your developers actually fixing the problem.

@sbauch https://github.com/sbauch question about I’m not sure how the “custom domains for email templates” impacts the SMTP settings, which supersedes, etc. is also very important before any of us can seriously consider using our own SMTP server in production.

Firebase Auth has always valued its developers and aimed to provide the best service to them. Once again, we apologize if you have encountered delays in our email delivery. The issue has always been due to some change in a third party email service provider which Firebase Auth used for email delivery, a service which we have no control over. Since then, we have been actively working on migrating to a new service which requires a lot of time and effort to complete. We really appreciate your understanding and patience on this issue.
