Shopify Inbox
Shopify Inbox is a mailbox that lets you offer customers the ability to chat with you from your online store and in the Shop app. From Shopify Inbox you can respond to customer messages, send product links, send discount codes, and send images.
You can access Shopify Inbox on your desktop at inbox.shopify.com, and through an iOS mobile app and Android mobile app.
When customers send you messages, you can respond from your desktop or mobile device, and manage conversations across staff members.
