batch emails in quickbooks online

Good morning, @Reno141. 

It's great to see you back in the Community! I'd be more than happy to provide you with some information about sending an email to all of your customers. 

You can easily email all or more than one of your customers in a batch by doing the following steps: 

1. Hover over the Sales tab on the left-hand menu bar. 
2. Select Customers. 
3. Put a check in the box on the right-hand side of each customer you'd like to email. 
4. Scroll back up to the top of the list and hit the drop-down arrow on the Batch Actions button. 
5. Choose Email.

This should do the trick. If you have any other questions, don't hesitate to come back. Have a wonderful day!
