A snapshot of the success story

Project Overview

A digital marketing agency was generating plenty of quality leads but couldn't reach them fast enough. Their sales team averaged 3–4 hours to respond, and some leads waited until the next business day.

That delay is expensive. Harvard Business Review research found that companies waiting even one hour to respond are 7 times less likely to qualify a lead — and 60 times less likely after 24 hours.

The agency needed to engage every prospect instantly, while filtering out the spam and unqualified inquiries eating their reps' time.

Delivering the Right Approach

Solution

We paired Make.com with Retell AI's conversational voice technology to build an agent that calls every new lead within minutes, qualifies them in natural conversation, and hands the promising ones to sales.

Instant Lead Response

The agent calls within minutes of a form submission — while the prospect is still at their desk researching solutions. It introduces itself transparently as an AI screening call, then leads a natural conversation about the prospect's needs.

Because it never sleeps, the agency now engages every lead inside the critical first hour — including nights, weekends, and busy periods.

Intelligent Qualification Screening

Through conversational questions about scope, timeline, budget, and decision-making authority, the agent scores each lead. Qualified prospects are connected to an available rep or booked for a follow-up; unqualified ones are politely wrapped up and tagged in the CRM.

The agent also spots spam submissions from interaction patterns, so reps never waste time on fake leads.

The Impact

Summary

Within the first 90 days, lead qualification rates rose 10% and the sales team became 32% more productive — reps now spend their time exclusively on pre-qualified opportunities.

Prospects noticed too: satisfaction scores improved once every inquiry got immediate attention instead of an hours-long wait. And spam submissions — previously about 15% of all form completions — stopped consuming any human time at all.
