Which three support channels are recommended for a client starting the process of building their support model?

In building a support model, it's crucial for clients to establish clear and effective communication channels that cater to their needs. The choice of #help-slack is particularly relevant because it serves as a dedicated space for users to ask questions, share experiences, and provide tips on using Slack more effectively. This channel can facilitate direct engagement among users and support staff, encouraging a community-driven approach to resolving issues.

By utilizing #help-slack, clients can create an environment where support inquiries can be addressed quickly and efficiently while fostering user collaboration. This also allows for gathering feedback on common issues, which can help improve the overall support model over time. In contrast, the other channels may not focus specifically on the broader community support aspect that #help-slack emphasizes, making it a more suitable choice for clients in the early stages of developing their support strategy.
