I’m sending emails which say sent but aren’t being received by my customers

Hello, Ajdelectrical. There are a few reasons why emails may show as sent in QBO but are not appearing in your customer's inbox. Often, this is due to the recipient's email security settings or spam filters.

To verify if the issue is on your end or the recipient's, you can try sending a test invoice to an email address you own (such as a personal Gmail or Outlook account). If you receive the test email, the system is working correctly, and the issue is likely specific to your customer's email provider.

Please also ask your customers to check their Junk or Spam folders. If they still can't find it, try clearing the email address, retype it manually, and save it before sending again to ensure there are no hidden spaces or errors.

Please let us know if you have further questions. We're here to help you anytime.
