Which Channel for an AI Customer Service Bot? A Field Guide
The channel decides more about your agent's behaviour than the model does. Where your customers already are, what each channel is mechanically bad at, and why you should launch one, not four. A two-location yoga studio rolled its AI agent out on three channels in a single week: Instagram DM, web chat, and SMS. On Instagram it answered around 300 messages in the first week but could not reliably…
Choosing a channel for an AI customer service bot is more important than the model itself. Where customers are, what each channel struggles with mechanically, and when to launch determines success. A yoga studio tested three channels: Instagram DM, web chat, and SMS in one week. On Instagram, the agent answered around 300 messages but couldn't send a working booking link.
Web chat showed most conversations stopped after the first reply, resulting in no bookings. SMS performed well, handling about forty messages weekly with almost no customer complaints. Despite using the same agent, facts file, and model, the results varied significantly due to channel differences. This highlights the importance of choosing the channel first and the platform second.
The channel dictates message length, latency expectations, media types, conversation identity, and normal behavior. The model remains consistent across channels, but customers do not. Each channel has its own unwritten contract. For instance, DMs feel like texting a person, demanding quick replies of two sentences or less. Email is a letter, expecting no immediate reply.
Web chat requires immediate attention or abandonment, while SMS is short, urgent, and less welcome when overused. Understanding these contracts helps set realistic expectations and avoid mismatches between the model and channel. Different channels have their own weaknesses. SMS splits messages at 160 characters, causing fragmented and sometimes out-of-order replies.
WhatsApp excels at short, structured exchanges but has limited flexibility with free-form replies. Web chat is best for visitors already on the site with buying intent, but silent abandonment after the first reply can be disastrous. Instagram and Facebook DMs are ideal for discovery but can be chaotic with mixed sales enquiries, spam, and support.
Email is great for detail-heavy queries and record-keeping but is slow and doesn't fit the expectation of immediate replies. A comparison table outlines the best use and main trap for each channel. The WhatsApp 24-hour window is particularly tricky, where outside this window, only pre-approved templates can be sent. Designing follow-ups around approved templates is crucial.
Starting with one channel and avoiding the temptation of multiple channels simultaneously is recommended. Analyzing last month's enquiries to determine the primary channel can save time and eliminate confusion. Channels with 80% of enquiries are ideal. Lastly, match the weakness of each channel to your tolerance. If web-chat abandonment is a problem, providing more human supervision may be necessary.
