Notifcation when email address is added to SendGrid Internal email suppressions list

When an email is sent out via SendGrid, internal we and the customer have no tracking for these email available in their workspace, for example if a notification email for a new order is not being received our customer would have no way of telling why this may be happening. Sometimes an email address may not be found when trying to send out these emails, and this will add them to the email suppression list in SendGrid. A notification under the settings in this case would allow the customer to see if there were an issues with these email being delivered previously, and an option to remove this address from our SendGrid internal email suppression list would allow them to resolve the issue without needing to contact us to investigate the issue.
