ShopMessage’s Facebook Messenger Marketing platform drives sales for Shopify and Shopify Plus merchants using Facebook Messenger. Pros: It’s easy to set up and easy to use. Your store visitors will receive targeted, personalized Facebook Messenger messages automatically. With one-click subscriptions, you can grow your Messenger list quickly. Drive sales with abandoned carts, browse abandon, welcome series, upsells, shipping notifications, custom Messenger menus, and campaigns. Cons: Some reviews indicate that the app itself has issues and it is difficult to send customer messages. Their negative reviews also mention their support and responsiveness. Only a few integrations are available. As a result, you may not be able to integrate it into your existing technology stack.
