Is there an additional setting for emails to be sent? I hit send when complete and they never leave.

It's nice to see you here in the Community, John. Thanks for reaching out to us.

I'm here to help you send emails in QuickBooks Online (QBO).

Setting up the company's email address you use for sending emails in QuickBooks Online (QBO) is pretty easy.

Here are the steps:

1. Click the Settings icon at the top and select Account and Settings.
2. Choose Company and click the Pencil icon on the Contact Info section.
3. Enter your email address in the Company email field and put a checkmark on the Same as company email.
4. Click Save, then Done.
    

If everything was all set, you may experience browser-related problems resulting in issues when sending emails. The system sometimes behaves strangely when the browser is full of outdated pages. The cache stored in your browser may be causing the issue. I suggest performing some basic troubleshooting steps to isolate the issue.

Let's begin by signing into your account using a private window. Here are the keyboard shortcuts depending on your browser:

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If this works, you'll need to return to your default browser and clear the cache. If not, try another supported browser.
