The WP Affiliate Platform (plugin to recruit and manage affiliates for your products) can be easily integrated with MailChimp (Email marketing and Email list manager).
To integrate MailChimp with WP Affiliate Platform simply go to the “Autoresponder Settings” tab from the Settings menu of the affiliate plugin and set it up.
This will make it so after an affiliate registers on your site, the user will automatically get added to your Mailchimp list.
Using MailChimp Interest Groups
You can add interest groups when a customer is added to your MailChimp list too.
Add the interest group data in the “List Name” field of a product like the following:
List Name | groupname1, groupname2
Lets say you have the following scenario:
List Name: my-list-1
Interest Group Names: groupname1, groupname2
Then you would enter the following in the list name field of the eStore product configuration:
my-list-1 | groupname1, groupname2
