OTP emails are going to spam in gmail [production issue]

Hello, we have been using Auth0 for our authentication for nearly 2 years now. Over the past 2 days, all the verification emails are ending in our spam on gmail (for business)

Stack: Auth0 Universal login on our Capacitor based mobile app

What could be the issue and how can we fix this?

Hey Kaushik. Thanks for reaching out to community.

If you or your org uses custom email provider for sending verification or pwd reset emails then I would request you to contact the email provider for the same as E-mail provider uses filtering software with rules that block the e-mail.

Depending on the e-mail provider and filtering software, the steps to solve may vary, but the concept is the same: the receiver of the e-mail or the IT Administrator in charge of the filtering software must add a rule to allow all e-mails from the blocked e-mail address to prevent the e-mail from being filtered to the spam folder. Here is an example for Gmail - Add users to safe senders list

Thanks !!

We got this issue fixed. There was nothing going on Auth0 but it was some DNS config changes on Mailgun (which is plugged to Auth0).
