Why am I only getting email notifications sometimes when a submission is made?

We are sorry for the inconvenience.

Can you please share to us a submission in which the notification email was not sent?

I have checked your form and it seems you have two email recipients. May we know what email address is not receiving the notification email?

Checked the mail logs and it seems the notification emails are sent correctly.

Can you please try whitelisting our IP addresses and Domains?

Looking forward for your response.
