Address book importing

we have migrated shopping cart programs from os commerce to zen cart, is there any way to move the customer list and emails so we can add them to our new newsletter?

What software are you using for the newsletter? There’s an Announce List here where you can populate it with your customer list and have it email them so they can opt-in to the Announce List.,PHP%26_Databases/_Announcement_Mailing_List

thank you but it seems were trying to use the native shopping cart newsletters so it requires an SQL database, and I am wondering if we can move the customer lists over to the new database
