Has anyone created a list of customer with their email address?

Thanks for reaching out to the Community, hansen-doug-yaho. Let me guide you in creating a report containing this information. 

We can generate a list with your customers and their email addresses by running a Customer Contact List Report. 

Here's how to do it:

1. On the left panel, select Reports. 
2. Type Customer Contact List in the search box.
3. Make sure you're in classic view.
4. Click the Settings button located in the upper right-hand corner.
5. Under Change Columns, put a checkmark on the Customer and Email box.
6. Click Run Report.
