You can export an email list in CSV from Klaviyo. To export an email list click “Lists & Segments” from the bar on the left-hand side of the dashboard and open the list you want to export. When you open a list, you will see a “Manage List” button at the top right corner of the page. Click the button and select the option, “Export List to CSV” from the drop-down menu. If you only want to export the email addresses, press the “Start Export” button on the next page to start the export. If you also want to export contact properties like address, phone number, and country you can also select these options before starting the export.
