At the moment, there is no way to track the lead response time, however, you can create an idea and let other community members to vote for it: https://community.manychat.com/ideas
Hey Sumit ,Since ManyChat doesn't have a native stopwatch for this yet, most high-ticket coaches are moving away from 'tracking' time and focusing on 'Instant Qualification.'
The reason response time matters is that leads get cold. If you send them a LeadVett link immediately in the DM, the AI qualifies them in 10 seconds. You don't have to 'track' how long it took you to get back to them because the 'Decision Engine' has already told you who is Gold and needs a call right now.
It effectively brings your 'Time-to-Value' down to under a minute. Might be a better fix than just a tracker? leadvett.com
