When users sign up it is expected they receive a verification email
Verification emails are received only by users with @gmail.com emails.
Verification emails are not reaching users with other email providers.
The same situation when triggering the verification email from Auth0 ‘User Management’ section for a particular user with non-Gmail email provider.
Our email providers are Amazon SES.
Error type from logs is
Email address is not verified. The following identities failed the check in region US-EAST-1.
I have seen a related unsolved old topic on the forum New accounts - problem sending out verification emails .
In which ways could I try to solve my case? Thank you for all the ideas!
