Hello there, @tcolon.
Here are the troubleshooting steps so that you can send an email.
The first option, reset your email address:
- Sign in to your QBO account.
- Go to Settings and click Account and Settings.
- Choose the Company section, then select Edit in Contact Info.
- Review each email address and make changes as needed.
- Click Save, then Done.

The second option, clear and re-enter your email address:
- Follow the second and third steps above.
- Clear the Company email field and enter the desired address as is, even if it appears correct.
- Click Save, then Done.
- Send yourself a test transaction.
If the email still hasn't arrived, consider using an alternate email address with a different domain. For example, if you were originally using a Gmail address, try switching to a Hotmail or Yahoo address instead.
If the two solutions are unsuccessful, you should set up the server to accept hostnames and IP addresses from the QuickBooks Online mail server. For more information, please visit this article: Configure server to accept QuickBooks Online mail server hostnames and IP addresses.
