We are now having this issue with our company as well. So far it only happens with emails that all go to a particular management company, but since that company covers at least four businesses it is quite a hassle to now have to PDF all of the invoices and email them with the payment link. A huge time waste. I know the email are correct as we use those emails to send the invoices through Gmail. They worked every month until they suddenly all started bouncing in November. The clients say their email shows no attempt at delivery.

I came to research what might be going on and I must say, I am absolutely disgusted to find that this has been an ongoing problem for people for over a YEAR with no resolution. If this starts happening to more clients for us, we will absolutely be taking our business elsewhere as we can't afford the extra time it takes to PDF and email every client, and I no longer have any trust that you are even working to fix this issue. There is no excuse for it taking that long.
