Thank you for bringing this to our attention, CaseyHart.
I'm here to ensure you can efficiently use the email services and that invoices are automatically sent to your customers. Let's configure your email settings to fix the issue.
If you're using the online version, I recommend that your customers set up their emails and allow Intuit addresses to go to their inbox, as suggested by @Rustler. This is because Intuit uses quickbooks@notification.intuit.com as the default email address when sending sales transactions.
However, if you have the desktop program, connect your email to QuickBooks so you can send invoices, reports, and other entries. Before you begin, make sure you have Outlook 2010 or later, as well as an Outlook email profile. When you're ready, follow the instructions in this article to link your email to QuickBooks Desktop.
I've included some articles to help you troubleshoot email issues in each QuickBooks version:
Some of the articles are from another region, but the solution steps are still applicable in the AU version.
If you have any additional questions about sending invoices or other QuickBooks-related concerns, tap the Reply button and enter them in the field box. I'll gladly respond to them for you. Have a wonderful day.
