Is there a way to easily gather email addresses from recent purchasers

We are wanting to send a thank you email for our customers that purchased over the holiday season, but there are more than 250 individual customers. I was hoping not to go through one by one and copying their email to a new sheet, and was wondering if there was an easier way to gather all of their emails easily or at the same time through the customer lists.

Would exporting the customers help for you?
