Hello there, Gnlman. QuickBooks Online uses its own mail servers to sales forms. This ensures high deliverability, meaning the emails are less likely to be marked as spam because Intuit’s servers are already trusted by major email providers.
You cannot access this domain. It is a no-reply email used exclusively to deliver notifications. You don't have an inbox there, and your customers can't reply to it.
On the other hand, if you'd prefer to have invoices or estimates sent from your personal email address, you can connect your Gmail account.
You can reply here if you need further assistance. We're here to help.
