Hello vargemdecorators, thanks for posting on the Community
Here are three possible reasons why your customers may not be receiving invoices and estimates sent from QuickBooks, and how you can fix the problem.
Solution 1: Reset your email address
If you recently imported QuickBooks Desktop data into a QuickBooks Online company, you may need to reset your email address:
1. Sign in to your QuickBooks Online account.
2. Go to Settings ⚙, then select Account and settings.
3. Go to the Company section, then select Edit ✎ in Contact info.
4. Review each email address and make changes as needed.
5. Select Save, then Done.
Solution 2: Clear and re-enter your email address
If solution 1 doesn't apply, ask your customers to check their junk mail and spam folders. If the email is still not found, clear and then re-enter your email address.
1. Go to Settings ⚙, then select Account and settings.
2. Go to the Company section, then select Edit ✎ in Contact info.
3. Clear the Company email field and enter the desired address as is, even if it appears correct. (Note: Be sure not to use any extra characters or spaces before, within, or after the address)
4. Select Save, then Done.
5. Send yourself a test transaction.
6. If you still don't receive the email, try using a different email address that has a different domain (for instance, if you were using a Gmail email address, try a Hotmail or Yahoo address instead).
Solution 3: Configure server to accept QuickBooks Online mail server host names and IP addresses
If the first two solutions don't work, ask an IT expert to help you with the following solution. The IT expert needs to add the QuickBooks Online mail server host names and IP addresses to your outgoing mail servers allowlist. This is so your QuickBooks emails aren't mistakenly marked as spam.
The steps to add the host names and IP addresses depend on your email setup. See our guide for a list of the Host Names and IP addresses that your IT expert needs to add to your allow list.
