Email invoices not going through to client

Hi benny_c2000-yaho,

Thanks for posting in the Community! Let me share with you the possible reasons why invoices are not received and on how to fix the problem.

First thing we'll need to do is to ask customers if they've check their spam or junk folders. If the email is not found, let's try to clear and re-enter your email address on your company's settings.

1. Go to Gear icon ⚙, 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.
4. Select Save, then Done.
5. Send yourself a test transaction.

Also, you may enable an option on your company settings if you would like to receive an email copy on your email address. You can do that by following these steps.

1. Go to Gear icon ⚙, then select Account and Settings.
2. Go to Sales. 
3. On Messages section, tick on Email me a copy at (your email address).
4. Select Save and Done.

If these solutions don't work for your, you may need to ask an IT expert to have the QBO mail server hostnames and IP addresses added to your outgoing mail servers.
