Passwordless code email takes several hours to send

[YUKA]

Hello.

There has been a significant delay in receiving the OTP code email for passwordless login. It took at least 1 hour to 6 hours after I clicked the Submit button.
I have set up SendGrid as custom mail provider based on the following thread, but this does not solve the problem.

Passwordless Code Email arrives 2 hours late (Wordpress Integration)

We have been experiencing times where the passwordless code email is shown as “Code/Link Sent” on the log but arrives about 2-3 hours late. Sometimes it arrives without problem, but from last December we have been experiencing this issue from time to time even though we haven’t changed any of the settings on auth0. Thank you for your support, Ayaka

The test email after setting up the email provider was sent within a few seconds.

Can anyone help me to solve this problem?

Thanks.

Hi @YUKA,

Welcome to the Auth0 Community!

I understand that you’ve encountered delays with the Passwordless code email.

In this case, could you please check your logs with SendGrid to monitor the behavior?

Looking forward to your response.

Thank you for the reply, @rueben.tiow .

I checked Sendgrid Activity Feed.

It says that the email has been processed and sent…

I confirmed that the email was delivered to my spam box…

Sorry…

Thank you for your help.

Best regards.
