Changes to email invoice not being sent

Welcome to the QuickBooks Community, @Ironwood-mfg.

I want to ensure you can save the message in your email invoice. Let's run some troubleshooting steps to get this fixed.

Changes in the body of the email should reflect to the emailed invoices. Since it doesn't reflect any of the changes made, let's make sure your QuickBooks Desktop (QBDT) is updated to the latest release. This will install the newest features and fixes. Let me show you how.

1. Go to the Help menu and select Update QuickBooks Desktop.
2. Select the Update Now tab.
3. Click Get Updates to start the download.
4. When the download finishes, restart QuickBooks.
5. Then accept the option to install the new release.

If the issue remains, I recommend running the Verify Rebuild tool. This scans your company file for errors and quickly fixes them.

Come back to this post and let me know how the troubleshooting steps go, @Ironwood-mfg. I'll be around to provide further assistance. 

I've also added these links that provide detailed steps on how you can personalize your sales forms and record invoice payments: 

• Use and customize form templates
• Record an invoice payment

Have a good one!

Sorry for the late reply. I went through the steps in your post and the computer was already up to date, we have it set to automatically update. Unfortunately, the issue is still there. I'm wondering if deleting the template and adding it again will resolve the issue?
