How did we segue to matching online bank feeds??

Anyway, I have never had so many bounced emails in QBO since I upgraded to Advanced. Yes, it would be great if a reason (or at lease more detail) was provided. Most times my invoices go out to multiple email addresses, it would be nice to know if any of them got through.

The only error message is "bounced email".

I'll hit 'resend' several times until it finally goes through... without changing anything. So if it goes through after the fourth attempt, with nothing changing... What could be the issue?
