If you use eCommerceTemplates and want to export the mailing list into Constant Contact, you can follow these steps. Make sure you have explicit permission from folks before you send them bulk emails!

1. Export from ECT store (Mailing List, Action: Dump Entire Mailing List)
2. Convert CSV file to XLSX (because CC needs this)
(Option: Break fullname (first last) into two columns or whether to leave it as one value)

4. Select which fields to import and map them to CC fields
5. Import and done.
