Cloud Kicks (CK) wants to provide its authenticated customers with a top-tier support experience. CK Ants to allow asynchronous conversations…

Messaging for Web is the modern Salesforce solution designed to provide a persistent and asynchronous conversational experience. It allows customers to start a conversation on one device and continue it on another, as the history is saved. This directly addresses the requirements for asynchronous and cross-device conversations. Furthermore, the Messaging for Web configuration includes features to display the Estimated Wait Time to customers before they initiate a conversation, managing their expectations and improving the overall support experience. This solution is specifically intended for embedding within external websites.

A. Einstein Bots: Einstein Bots can be used within a Messaging for Web implementation, but they are not the underlying channel that provides the asynchronous and cross-device capabilities.

C. AppExchange package: This is a generic suggestion. While a third-party solution might exist, Messaging for Web is the standard, native Salesforce product designed to meet these specific requirements.

1. Salesforce Help, "Compare Messaging for In-App and Web with Chat": This document explicitly contrasts the two technologies. It states, "Unlike Chat, Messaging is asynchronous, meaning that conversations can be paused and resumed at the customer’s convenience. Customers can even switch devices and pick up where they left off." This directly supports the asynchronous and cross-device requirements.

2. Salesforce Help, "Messaging for In-App and Web Overview": This guide introduces the feature, describing it as a way to "offer a continuous and persistent messaging experience to your customers on your website." This confirms its suitability for the scenario.

3. Salesforce Help, "Customize the Pre-Chat Experience in Messaging for Web": This documentation details the setup process, including the "Conversation Start Menu" component. It notes that you can add fields to this menu, including "Estimated Wait Time," which directly addresses the transparency requirement.
