How I Build Cold Outreach Lead Lists From Google Maps (Without Paying for Apollo)

Description and use

Building a cold outreach lead list from Google Maps without paid tools: collect, filter, enrich, store in a spreadsheet, then send personalized outreach.

Problem

Finding relevant contacts for cold outreach was costly and time‑consuming using paid tools.

Outcome

The pipeline produced a clean list of ~15,000 contacts with emails and ~8,400 with mobile numbers from an initial 29,000 listings, eliminating the need for paid enrichment services.

Workflow

• 1. Pull all business listings from Google Maps (e.g., 29,000 UK coaches).
• 2. Filter raw list by category keywords and basic signals to remove noise (resulting in ~11,700 good fits).
• 3. For each good fit, visit the business website and extract public contact info (email, socials, phone).
• 4. Store all data in a single spreadsheet with clear columns (fit status, contact info, source).
• 5. Conduct human‑centric outreach: short, personalized messages, stop after a single follow‑up if no response.

Evidence

For local and service businesses, the most up to date directory is usually Google Maps.

In that UK set, roughly 15,000 had a findable email, and about 8,400 of the good-fit ones had a mobile number.

We keep messages short, personal, and we stop the moment someone says no. One follow-up at most if they go quiet.
