What the research says
The most cited study is the Harvard Business Review audit of 1.25 million sales leads (Oldroyd, McElheran and Elkington, 2011). Firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it as firms that waited even one hour longer, and more than 60 times as likely as firms that waited 24 hours or more.
The same audit found that the average company took 42 hours to respond, and 23% never responded at all.
Why teams miss it
- Leads arrive when nobody's free. Evenings, weekends, during meetings.
- Calling is a context switch. Someone has to look the lead up before dialing.
- AI voices aren't a safe shortcut. AI-generated voices fall under the TCPA's artificial-voice rules. See our TCPA guide.
Build a sub-10-minute follow-up
- Trigger on submitFire a webhook from your form the moment it's submitted.
- Let an agent prepareHave your agent pull context (what they asked for, their site, past interactions) and write the brief.
- Hand the call to a human
create_call_taskwithdeadline_minutes: 30, so it's called fast or not at all. - Close the loopThe outcome webhook triggers the calendar invite, a recap email, or a nurture sequence.
Speed matters, but so do calling hours. Ring a Human only dials 9am–8pm in the lead's timezone. Leads that come in late are called first thing the next morning, unless the deadline has passed.
