Hello all. I’m Ami, one of the Moderators here in the QuickBooks Community. I want to thank everyone that participated in this conversation with more information about outbound emails being blocked/blacklisted.

I've escalated this to our engineering team for further investigation and will return to this thread with updates as I have them available.

Thank you to everyone for your diligence on this. We’ll do everything we can to find a swift resolution and make sure your invoices and other outbound emails are delivered reliably.
