Thanks for joining this conversation, @DavidJLive.
I can see how having the ability to use and customize your own domain to send email in QuickBooks Online (QBO) would be helpful for you and your business. That said, rest assured that I'll pass along your suggestion to our Product Developers. They're always looking for ideas to consider on how to improve QBO.
For now, I suggest visiting our Blog site. This is where we share recent happenings and future developments, such as updates to newly added features. Please refer to the link shared by my colleague above.
Just in case, I'll add this article for future reference: Send an invoice.
Please let me know if you have any other concerns by leaving a comment in this thread. I'm more than happy to help. Have a good one!
