I would like to have my emails sent from my own server. There are too many issues with customers/suppliers flagging emails as spam. Also there's a delay of at least 5 min
Thanks for posting here in the Community, @finance54.
I'm here to provide some insight into your questions about changing the sender email for invoices in QuickBooks Online.
The default email address when sending sales forms like invoices, transactions, and reports is firstname.lastname@example.org. Changing the sender email address in QBO is currently unavailable. Our engineers are working to add some options, such as connecting your Google Apps for Business account should you use their email services for your business.
If you have any further QuickBooks related questions, feel free to let me know. Have a great day!
