Mainly, all work with the Mailchimp lists and newsletters is conducted on the Mailchimp side. The Mailchimp Integration with eCommerce Support add-on in X-Cart allows viewing Mailchimp audiences uploaded to the store Admin area automatically and checking customers’ subscriptions. The audiences creation and management and the subscription lists management themselves are done on the Mailchimp side.
After you have connected your store to your Mailchimp account and configured the add-on Mailchimp Integration with eCommerce Support, Mailchimp audiences are automatically uploaded to the Marketing -> Mailchimp Lists section of your X-Cart Admin area:
For X-Cart 5.3.x and earlier, Mailchimp audiences are displayed in the Sales channels -> Mailchimp lists section.
Be sure to check this page and do as follows:
Use the ON/OFF button in front of the name of a specific list and group to specify the lists and groups that should be active for your store. The active lists and groups will be visible on the forms that your store users will use to select the lists/groups they want to subscribe to. Inactive lists/groups will not appear on such forms, and thus your store users will not be able to select them.
Use the checkboxes in the “Subscribe by default” column to specify which lists and groups a user should be subscribed to if they opted in to receive your store’s email newsletter via a single check box option (without choosing the specific lists/groups - for example, by subscribing via the “Sign up for _My_Store_ news” box in the site footer, or by choosing the option “Subscribe to our news list and be in touch with our latest offers” during checkout).
All Mailchimp lists you will see on the Marketing -> Mailchimp Lists page of your store Admin area are created and managed on the Mailchimp dashboard outside your X-Cart based store. For more info on Mailchimp lists (called “audience” there), see the Mailchimp Knowledge Base article.
Any lists and list groups configured in your Mailchimp account before your X-Cart store has been connected to Mailchimp are automatically imported into your store. However, if the actual state of your lists does not display correctly on the Marketing -> Mailchimp Lists page of your store Admin area (e.g., after the audiences/groups have been edited recently), use the Update Mailchimp Lists button on the add-on settings page in X-Cart to synchronize the data between the systems. For more details, see Uploading Store Data to Mailchimp.
In any case, you need to make sure that the audiences and groups you have configured in Mailchimp are visible on the Marketing > Mailchimp Lists page in your X-Cart store’s Admin area.
