How do I set up invoice eMail with Thunderbird?

Hello, @ToddAndMargo.

I'm here to make sure you'll be able to set up your email in QuickBooks.

Here's how:

1. Go to the Edit menu then choose Preferences at the bottom.
2. A pop-up window will appear, select Send Forms.
3. Under My Preferences tab, click Add to enter your email.
4. Enter your email and select the email provider then click Ok.
5. You can now see your email under My Preferences, click Ok to save changes.

You can also change customer email settings for recurring payments.

Let me know if you have additional questions by posting it here in Community. Have a great, take care.
