Am I able to export my contacts to my own computer?

Yes! If you'd like to export your entire list of contacts, simply login to 1Shoppingcart, and click on "Contacts" then "Export Contacts"

It will ask you to confirm the email address to send the exported list to. Hit the submit button when ready and it will email you a link to download the list.

You can also export certain list segments by first finding a certain list of contacts by doing a search in the contacts area.
