How to Build a Sales Prospect List — Step-by-Step Guide

June 2026  ·  8 min read  ·  By GrabNear

A prospect list is the foundation of any outbound sales effort. Without one, your team has no one to call, email, or follow up with. With a well-built list, you can run systematic outreach campaigns and measure what's working.

Here's how to build one from scratch — using free and low-cost tools that work for any business type, anywhere in the world.

Phase 1 — Define Who You're Targeting

Step 1
Write Your Ideal Customer Profile (ICP)

Before sourcing any contacts, define exactly who belongs on your list. Answer these questions in writing:

Step 2
Set a List Size Target

Decide how many prospects you need. A useful rule of thumb: if your close rate on outreach is 2%, you need 50 contacts to close 1 deal. To close 10 deals, build a list of 500. Set a realistic target before you start sourcing.

Phase 2 — Source Your Contacts

Source 1 — Google Maps (Best for SMBs and Local Businesses)

Google Maps has over 200 million verified business listings. Every listing has a business name, address, phone number, website, category, and rating — updated by the businesses themselves. For SMBs, local services, retailers, restaurants, clinics, agencies, and contractors, it's the most accurate and up-to-date business database available for free.

How to extract from Google Maps
Use GrabNear Chrome Extension (Free)

Install GrabNear, search Google Maps for your ICP (e.g. "accounting firms in Melbourne"), and the extension automatically extracts every business's phone, website, address and image into a list. Export to CSV with one click. Run 5 different searches and you have 300–500 contacts in an hour — all free, no account required.

Source 2 — LinkedIn (Best for Professional and Enterprise Contacts)

LinkedIn's search lets you filter by job title, company size, industry, and location. Use Boolean search operators for precision: "Head of Marketing" AND "SaaS" AND "London". Sales Navigator (paid) unlocks advanced filters and saves more searches. The free tier still lets you identify companies and decision-maker names.

Source 3 — Industry Directories

Many industries have professional directories that list member businesses — law societies, medical councils, chamber of commerce directories, trade association member lists. These are often free and highly targeted to a specific sector. Search "[industry] directory [country]" to find them.

Source 4 — Conference Exhibitor Lists

Industry conferences and trade shows publish exhibitor and sponsor lists on their websites. These businesses are actively spending money in your market, which makes them high-intent prospects. Scraping the list manually takes 30–60 minutes but produces a tightly qualified set of contacts.

Phase 3 — Enrich with Contact Information

Step 3
Add Email Addresses

Once you have company names and websites, find the contact email: visit the company website and check "Contact Us" or "About" pages, or use Hunter.io (25 free lookups/month) to find emails by domain. GrabNear's Deep Search visits each business website automatically and extracts the publicly listed email.

Step 4
Find the Decision-Maker Name

For small businesses, the owner is usually the decision-maker. Google "[company name] owner" or check the About page. For larger companies, search LinkedIn for the job title you identified in your ICP. Personalized outreach with a real name outperforms "Dear Sir/Madam" by 3–5x.

Step 5
Verify Before You Send

An unverified list wastes your outreach effort. Check that websites are live, phone numbers are active, and email formats are correct. NeverBounce (free tier available) verifies email addresses before you send. For phone numbers, a quick manual spot-check of 10% of the list catches most dead numbers.

Phase 4 — Organize the List

A disorganized prospect list is almost as bad as no list. Use these columns as a minimum:

Column What to Put Here
Business Name Full legal/trading name
Contact Name Decision-maker first and last name
Phone Direct phone number
Email Verified contact email
Website Company website URL
City / Country For segmentation
Source Where you found this lead (Google Maps, LinkedIn, etc.)
Status Not contacted / Emailed / Called / Replied / Meeting / Closed / Lost
Last Contacted Date of last outreach
Notes Anything relevant from previous conversations

Phase 5 — Segment Before Outreach

Don't send the same message to your entire list. Segment by:

A segmented list produces 2–3x better response rates than a single unsegmented blast.

Pro tip: Start outreach before your list is "complete." Send to your first 50 contacts, see what resonates, then apply those learnings to how you message the next 200. Waiting until you have 1,000 contacts means 1,000 messages using an untested template.
