User did not receive email - What to do?

[davidtopf2]

What I’m trying to do:
I have a registration process set up using the basic anvil signup functionality:

user = anvil.users.signup_with_form(allow_cancel=True)

This usually works well, but one user was screensharing and did not receive the email, even though the user was succesfully added to the users table.

What we checked:

• User was added to user table
• No email in inbox or spam even after 5 minutes

What I would like to know:

• Is this a known issue?
• How do I debug this issue?
• What can I do about it?

As each case leads to a lost user, this is crucial for me to solve.

I’m not aware of this being an issue. Can you replicate it? Where my mind goes is maybe they entered their email address wrong?

I’ll try to replicate it with her email address again. Good point.

The email was correct though, we checked that.

I’ll let you know what the result was!

I actually had a user who claimed to not receive the email two days ago.
She tried twice, checking the spam folder each time, but no email.

On a quick forum search, I found a couple potentially related reports:

I recently set a custom from address to match my domain for user related emails: password resets & email confirmations.

That led to the strange situation where emails sent from my debug environment arrived fine, but emails sent from any other environment did not arrive. After a brief exchange with Anvil support, it turns out my DMARC policy was causing those emails to be rejected.

We have occasional email deliverability issues. Sometimes users (claim to) never receive an email verification email.

Anvil email enquiry

I’ve observed instances where users do not receive ‘forgot password’ emails, and in some cases, these emails end up in the trash or spam folders. Is there a solution within Anvil to address this, or is it likely an issue related to the users’ email settings?
