Hey there, @john140.
Welcome to the Community! Glad to have you here. To ensure that I'm on the same page, are you wishing to send a new email to all of your customers, such as advertising a promotion? If so, you can accomplish this with the following steps:
- Click Sales on the left navigation panel.
- Select Customers at the top.
- Place a check-mark next to the customers that you need to email.
- Click the Batch actions drop-down and choose Email.
Should you need to batch send sales transactions, please refer to the following link: How to Email or Print Multiple Invoices and Sales Forms at One Time.
Hope you have a great weekend. Let me know if I can be of additional help.
