At PhotoBiz, we send email notifications for a variety of reasons—like membership renewals, form submissions, client gallery activity, ecommerce orders, password recovery, 2 Factor Authentication, and more. To help make sure these messages are delivered successfully, we use email validation to prevent our servers from being marked as spam.

If an email address rejects one of our notifications, it’s marked as non-deliverable and added to our bounced email list. This helps protect our email server’s reputation by avoiding repeated delivery attempts to invalid or problematic addresses.

Here are some common reasons an email might bounce:

• The email inbox is full and can't accept more messages
  
  
• The email address no longer exists
  
  
• Emails from us have been marked as spam
  
  
• There's a service outage with the email provider
  
  
• The domain’s MX records aren’t configured correctly

If an email ends up on our non-deliverable list, we won’t be able to send notifications (like billing emails, form alerts, etc.) to that address until it’s removed.

How to get an email address removed from the bounced list:
If a client lets us know they’re not receiving emails, we can manually remove their address from the non-deliverable list. Once removed, emails should start flowing again—but if that address rejects our messages in the future, it’ll end up back on the list, and we’ll need to manually remove it again.
