Hi Integrated,
Thank you for joining the conversation and for listing some consequences of not having the option to use your email as a sender. Let me add some points based on those.
As of the moment, we're unable to change the "From" email, unless you have a Gmail account. Yes, there's a chance an invoice will end up in the SPAM folder, but your customers can add quickbooks@notification.intuit.com to their exemption list or trusted addresses if they have that option.
About entering the wrong email, your Invoice page will display a delivery report below the payer's name, indicating whether it was sent or not.
As for using a Gmail account, I understand that most businesses use their business name as a domain. Having Gmail is only an option provided for those who have this email provider.
If you need to resend your invoice, you'll want to open it and send it like how you would normally send this transaction.
On the other hand, I appreciate your effort to send feedback about this matter. All we can do now is wait for changes as we're unable to rectify this particular request.
I also want to add that you can find articles on the main support page, should you need quick references in the future.
Let me know if you have any other concerns about QuickBooks. Take care and have a great day.
