This module synchronizes the list of subscribers to your Prestashop newsletter with your MailChimp mailing list.
Apart from automating the update of your MailChimp list and remove the tedious export of subscribers from PrestaShop then import them on MailChimp, the big advantage of this module is its two ways synchronization: - PrestaShop with MailChimp: when creating a customer account, when editing a customer account - MailChimp with Prestashop: at the subscription to the newsletter using the MailChimp signup form, at unsubscribe from the newsletter by clicking the unsubscribe link that must appear in the emails
This synchronization is done in realtime and doesn't need a cron task.
And the little plus is the block displaying a link to your MailChimp registration form.
In addition, your hosting doesn't need cURL extension because it is not used by this module.
