How to evaluate AI support agents

Resolution rateWhat percentage of tickets does the agent resolve without human intervention? Industry-leading agents achieve 60-80% autonomous resolution rates.
Escalation qualityWhen the agent cannot resolve a query, how well does it hand off to a human? Good escalation includes full context, sentiment analysis, and suggested next steps.
Channel coverageDoes the agent cover all the channels your customers use — email, live chat, SMS, WhatsApp, social? Omnichannel coverage matters as customers expect consistent service everywhere.
Integration depthHow well does the agent connect to your CRM, order management, and product database? Agents with deeper integrations can resolve more complex queries autonomously.
Training and customisationHow much work is required to train the agent on your specific products, policies, and tone? Faster time-to-value matters for time-constrained teams.
