Hi there, Garry. There are a few possible reasons why this occurs, ranging from invisible formatting errors to evolving security standards among email providers.
To ensure your invoices consistently reach your customers’ inboxes, we can perform a quick synchronization check of your email settings.
First, ask your customers to double-check their Junk or Spam folders. Because QuickBooks Online (QBO) sends emails on your behalf, some high-security filters might misidentify the invoice as spam.
If it's still missing, you’ll need to reconfigure your email setup. Let me guide you with these steps:
- Click the Gear icon and select Account and settings.
- Go to the Company tab and click the Contact info section.
- Clear out the Company email field entirely and type it back in manually. Ensure there are no extra spaces before or after the address.
- Hit Save and then Done.
Lastly, you can send yourself a test transaction. If you’re getting the same result, we'll have to use a different email address with a different domain.
If you have any other questions or need further assistance while using QBO, don’t hesitate to click the Reply button.
