Explain it simply
When someone answers a cold email (a sales email sent to a stranger) saying they're interested, a bot replies right away and books a call on the calendar. It follows written rules about the offer, who qualifies and when to ask the owner first, and it ignores out-of-office replies. Giving the bot just this one job helped the agency book 20 calls in 8 days.
What was done
The bot handles only replies and bookings; other bots do the rest. It reads a written charter on every reply: the offer, booking link, calendar rules, a qualification line (over $600K a year in revenue), tone, and when to ask the owner versus act. A webhook starts it the moment someone replies positively.
It drops out-of-office and "left the company" replies, logs unsubscribe requests without answering, and checks the thread so it never double-sends. When a lead picks a time, it books the slot, confirms and updates the CRM in the same run.
How it went
He reports 20 sales calls in 8 days for his own agency. The bot's own scorecard showed 60% of interested replies booked over the last 7 days.
- Limits: speed was the weak spot. Only 16% of first replies went out within the 3-minute target, partly because it waits for his approval on unusual cases. These are self-reported numbers from one week, and the post does not say how many calls became paying clients.
Prompt
- One yes/no time question ("does Tuesday at 9:00am CT work?") with the calendar link in a PS, not a menu of slots.
- Every call ask says what the prospect gets from the call.
- Qualification never blocks a booking: if revenue is unknown, ask "under or over $600K?" in the same email.
- Price question = one line. Every follow-up adds something new; the last one is a breakup email.
- Drop out-of-office and "left the company"; log STOP/remove, never reply.
- Before sending, check the thread for a reply that already went out.
- Act alone on times, bookings, reschedules and follow-ups; ask me about lead lists, CCs, borderline leads and odd pricing.His reply rules, summarized.
Business fit
Who this helps, and how:
Agencies and freelancers: answer warm replies within minutes and book calls without living in the inbox.
AgenciesLocal service businesses: reply to quote requests with one specific time offer and a booking link, day or night.
Local & serviceIndependent contractors (barbers, bartenders, consultants): consultants can let a bot handle "yes, interested" replies and scheduling.
AgenciesStartup founders and e-commerce sellers: convert positive outbound replies into demos while you build.
StartupsMechanics and tradespeople: reply to inbound estimate requests with a proposed appointment and log it in the job calendar.
