First Response Time

What it means

First response time is one of the most watched support metrics because it's the first moment a customer experiences your team's responsiveness. FRT is measured from ticket creation timestamp to the timestamp of the first outbound message on that ticket. In ecommerce, FRT expectations are shaped by channel: chat conversations have a sub-60-second expectation; email has a 1–4 hour expectation during business hours; social DMs typically 1–2 hours. Customers who wait more than 24 hours for any first response are significantly more likely to escalate, post negative reviews, or abandon the brand. AI agents change the FRT picture entirely. When an AI handles first response, FRT collapses to seconds regardless of time zone, day of week, or ticket volume. Even for tickets that ultimately need a human, a fast AI acknowledgment that sets accurate expectations ('I'm pulling up your order now — let me get that sorted') preserves CSAT while the human queue processes. FRT is distinct from resolution time. A fast first response doesn't mean a fast resolution — but it does meaningfully reduce customer frustration during the wait.
