ShopMessage’s Facebook Messenger marketing platform drives sales for Shopify and Shopify Plus merchants using Facebook Messenger. Pros: It’s easy to install and understand. With one-click subscriptions, you can quickly grow your Messenger list with targeted, personalized messages. Drive sales with abandoned carts, browse abandon, welcome series, upsells, shipping notifications, custom Messenger menus, and campaigns. It appears to be difficult to send messages to customers and to have problems with the app itself, according to some reviews. In addition to the above point, their support and responsiveness have been cited in negative reviews. Only a few integrations are available. You may not be able to integrate it with your existing tech stack.
