How can i send an email to all customers?

Hello there, @nshorepools-aol-.

QuickBooks has the option to send emails to customers in batches. I'll be glad to show you how.

Here’s how.

1. Click Sales on the left navigation panel.
2. Select Customers at the top.
3. Place a check-mark next to the customers that you need to email.
4. Click the Batch actions drop-down and choose Email.

I've also included a detailed resource about emailing sales forms which may come in handy moving forward: Email sales forms. 
 

When you're done, you can check out these topics to help you manage your sales and customers in QuickBooks Online: Sales and customers. 

Keep me posted if you need anything else about sending emails to customers in QuickBooks. I'm always right here to share some insights about it. Take care
