ProductCart Modification:
Constant Contact API Integration
This add-on allows newsletter subscription preferences to be automatically written to your Constant Contact mailing list using the Constant Contact API.
From the site visitor's perspective, this mod is virtually seamless. You plug it in and anywhere (new customer signup, checkout and "my account" settings) that ProductCart would normally allow the visitor to elect to specify their e-mail preferences, the mod takes over and causes those choices to be sent directly to your designated mailing list at Constant Contact - in addition to maintaining the correct choices within your ProductCart customer database table..
This script plugs into the ProductCart admin tools and provides an easy-to-use interface where one may configure the various settings.
Please click the image below for a larger (scrollable) view of the Constant Contact settings admin screen.
