Hi there, Laura194. There are several reasons why your clients aren't receiving your invoices.
There's a chance that invoices land in the junk or spam folders, so we recommend asking your customers to check there first. If they don't find them there, clear and re-enter your email address in your QuickBooks account:
- Go to the Gear Icon, then select Account and Settings in your QBO account.
- In the Company section, select Edit ✎ beside Email.
- Clear the Company email field and enter the desired address as is, even if it appears correct.
- Click Save, then Done.
After this, send a test transaction to yourself. If it doesn’t show up, consider using an email address with a different domain.
If previous solutions do not resolve the issue, it may be due to server problems. We recommend contacting an IT expert to assist you in accepting QuickBooks mail server host names and IP addresses. You can find more information about this in Solution 3 of this article: 3 solutions for when customers aren't receiving your emails.
