Company name font changes in email

I'm here to help you sort this out, Jkavafian.

When you email an invoice to a specific customer, select the template you’ve created. Open the invoice and select the preferred template from the Template drop-down menu. For your visual reference, I've attached a screenshot below.

If the issue persists, I recommend running the Verify and Rebuild tool. This will detect any damaged data and fix it by rebuilding. It also allows the program to refresh your file. 

Beforehand, let's update QuickBooks Desktop to the latest release to have the latest features and fixes.

Follow the steps below on how to verify data:

1. On the top menu, click File.
2. Choose Utilities.
3. Select Verify Data.
4. Click OK if QuickBooks doesn't detect a problem with your data.
5. If Verify finds an issue with your data, you'll be prompted to Rebuild Now or View Errors.
6. Click Close or View Errors and take note of the specific error message.

Next, here's how to rebuild data:

1. On the top menu, click File.
2. Choose Utilities.
3. Select Rebuild Data.
4. Click OK if you receive a prompt to back up your company file.
5. Click OK when you get the message, Rebuild has completed, and proceed to the next step.
6. Run Rebuild Data again to make sure there's no error.
