Bounced emails refer to emails that cannot be delivered to the intended recipient and are returned to the sender. An email can bounce for various reasons, including the recipient's email address being invalid, the email server being temporarily unavailable, or the recipient's inbox being full.
When you enable Receive email notification, you want to be notified whenever someone fills out the form. We believe this is an important notification, as the recipient might have to perform certain actions after form submission, like scheduling a call or evaluating the applicant. If this email bounces, then there would be no way for the recipient to know that a submission occurred.
To prevent that, NeetoForm notifies all the workspace admins via email when an email delivery fails to reach the intended recipient. This bounce notification email assists in identifying issues such as incorrect or invalid email addresses, thereby prompting the necessary corrections on the Receive email notification page.
