The Mailchimp plugin allows you to integrate your online store with Mailchimp newsletter- and email marketing service by syncing your customers and their purchase data to your Mailchimp account. This allows you to send targeted campaigns, automatically follow up with customers post-purchase, recommend products, recover abandoned carts, and measure the ROI of your marketing efforts. 

With this plugin, you can remind customers of items they left in their cart or looked at on your site. You can showcase product recommendations, track customers based on their purchase history and frequency. You can integrate Facebook and Instagram Ad campaigns in Mailchimp and acquire data about your marketing performance. By adding a pop-up you can convert your online shop visitors to subscribers. And, you can integrate discount codes in your emails with a Promo Code content block.
