How do you put in two separate email address's for one invoice?

Welcome to the Community, @lori74. I'm here to walk you through entering multiple email addresses in the Customer information so you won't have to add it in every invoice. 

All you need to do is to use a comma to separate the email addresses. Example: abc@yahoo.com,def@yahoo.com. 

Here's how: 

1. Go to the Sales tab, then choose Customers.
2. Select a customer.
3. Click the Customer Details tab, then click Edit.
4. Enter the email addresses in the Email field.
5. Click Save.

Please know that there's a limited number of characters that can be entered in this field.

For future reference, read through this article: Create templates for recurring transactions. It helps you learn about adding different email addresses for a customer when creating any sales forms. 

I'd be here to help if you have additional concerns. Take care.

Hi @lori74,

Hope you’re doing great. I wanted to see how everything is going about entering two separate emails you had yesterday. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.

Looking forward to your reply. Have a pleasant day ahead!

got it, Thank you. 

For people who use Outlook, separate with a semicolon instead of a comma.
