We have SendGrid setup as our external email provider. In SendGrid, we have an authenticated domain, eg. ‘firstname.lastname@example.org,’ in addition to single sender emails, eg. ‘email@example.com’ and ‘firstname.lastname@example.org’.
I then went into the ‘Email Templates’ section in Auth0 to configure the ‘Change Password’ email template and set the ‘from’ email as the ‘email@example.com’. When testing the password reset flow, we got emails for other domains like gmail and hotmail, but not for the email of the same domain, ie. ‘@fakeemail.com’. However, Auth0 logs showed that those emails had been sent successfully. The emails weren’t even delayed, never received.
Considering that the domain was an issue, the ‘from’ email was then updated to ‘firstname.lastname@example.org’ and it worked just fine. Do we potentially need to update our authenticated domain in SendGrid to use ‘email@example.com,’ as that is our preference, or can this be fixed in Auth0?
Thank you in advance!
