Building a niche prospect list for a client used to mean hours of manual research, a pricey database seat, or a CSV full of bounced emails. There is a faster path: type the client's trade and location once, preview live results pulled from public Google Maps listings, and export an email-enriched file without the manual research. This guide explains the exact workflow, what it costs, and where the honest limits are.
Key takeaways
- Type one query — trade plus location — and get a list of business names, addresses, phones, websites, and enriched emails in a single step.
- LeadGrid charges a one-time credit fee per search (from $9 for 3 credits), not a monthly seat, so agencies can run client lists without paying a recurring subscription for each niche.
- Email enrichment pulls contact addresses from each business's own website, which matters because roughly half of businesses with a website still list no email on Google Maps.
- Export to CSV/Excel or push directly to HubSpot as Companies; credits never expire and re-downloads are free for 30 days.
- This approach suits agencies doing local or SMB outreach; it is not the right tool if a client needs personal LinkedIn profiles, enterprise org charts, or high-volume intent data.
What is the fastest way for an agency to build a niche prospect list for a client?
The fastest method is to run a single trade-plus-location search against a live public-listing database that also enriches email addresses automatically — skipping manual research, browser plugins, and spreadsheet merging entirely. For agencies handling multiple client niches, a pay-once-per-list tool beats a per-seat subscription that charges you every month whether you use it or not.
Most agencies waste time on two failure modes: paying a large subscription for a database they underuse, or hand-building lists from Google searches that take hours and still miss contact details. LeadGrid sits between those extremes — it queries public Google Maps listings in real time, then enriches each result with an email scraped from the business's own website when Maps carries none. The output is a clean, current list rather than a snapshot from a database that was last refreshed months ago.
The honest trade-off: if a client's ICP is enterprise buyers, named decision-makers, or LinkedIn-connected contacts, this is not the right starting point. LeadGrid covers local and regional SMB businesses — dentists, law firms, restaurants, contractors, accountants — the kinds of targets where the business itself is the prospect, not a specific person inside a 10,000-person company.
How do you actually run the search and build the list?
Running a niche prospect list on LeadGrid is a short sequence from blank screen to exported file. A search returning up to 50 businesses costs one credit, and larger pulls spend multiple credits.
- Open LeadGrid and type the client's target trade and location in plain language — for example, 'dentists in Florida' or 'accountants in Austin TX'. No Boolean strings required.
- Preview the first results to confirm the niche and geography are returning relevant listings before committing credits.
- Purchase the credit pack that matches your expected volume: $9 buys 3 credits — roughly three 50-lead searches, fewer if you run larger ones; $29 buys 12 credits — roughly a dozen 50-lead searches, fewer if you run larger ones; $79 buys 36 credits — roughly three dozen 50-lead searches, fewer if you run larger ones. Credits never expire, so unused credits roll to the next client.
- Run the full search. Each credit covers one search of up to 50 results; larger lists spend multiple credits automatically. LeadGrid enriches each result with an email found on the business's own website where Google Maps has none.
- Review the list — name, address, phone, website, email — and remove any entries the client flagged as existing customers or already-contacted prospects.
- Export to CSV or Excel for the client's own CRM, or use the one-click HubSpot push to create Companies records directly. Re-downloads are free for 30 days from the same search.
That enrichment step is why the list is usable on day one rather than after a separate email-finding pass. A tool like Hunter can find emails too, but it charges a monthly subscription (~$34/mo) and returns no phone numbers — meaning you still need a second source for the phone column.

How does LeadGrid's cost compare to subscription tools for agencies running multiple client niches?
For agencies running five or more distinct client niches per month, the subscription model of most lead databases creates a structural cost problem: you pay the same monthly fee whether you run two searches or two hundred. LeadGrid's one-time credit packs mean each client list has a discrete, predictable cost — at the Bulk tier, $79 buys 36 credits, roughly three dozen 50-lead searches, fewer if you run larger ones — with no seat fee attached to an account that sits idle between projects.
| Tool | Pricing model | What it is | Best for |
|---|---|---|---|
| LeadGrid | $9–$79 one-time credit packs; no subscription | Search over public Google Maps listings, with name, address, phone, website, and email enriched from the business's own website | Agency niche lists, local/SMB outreach |
| Apollo | ~$49+/user/mo; metered exports | B2B people database | Sales teams prospecting named contacts |
| Hunter | ~$34/mo | Email finder; no phone numbers | Email finding when you already have a domain |
| ZoomInfo | ~$15k/yr | Enterprise platform | Large enterprise sales orgs with budget |
| D7 Lead Finder | No price quoted here | Directory scrape; high volume but stale/bouncy | High-volume scraping when you can tolerate a noisy list |
The honest caveat on raw cost-per-row: high-volume scrapers like D7 Lead Finder can produce more rows for less money, and LeadGrid is not the cheapest per row. The trade-off is that D7's output is high volume but stale and bouncy, in our view. LeadGrid pulls from public Google Maps listings and enriches emails from each business's own website, so the list is cleaner and more current. If a client needs 10,000 leads immediately and is comfortable cleaning a noisy list, a scraper may win on unit economics. If they need a list they can actually send to without burning a domain, cleaner data earns its cost.
Is it legal for an agency to use Google Maps business data for outreach on behalf of a client?
Rules vary by jurisdiction — confirm your own lawful basis for outreach; LeadGrid honors removal requests within 48h.
LeadGrid surfaces only public business listings — the same data visible to anyone searching Google Maps. It does not access LinkedIn profiles, social media accounts, or any login-walled source. If a business asks to be removed, LeadGrid honors the request within 48 hours.
Because LeadGrid is built around business listings rather than individuals, it fits B2B prospecting for local and regional companies. Agencies should agree with the client up front who is responsible for the outreach itself. For a fuller treatment of the lawful basis question, see the guide on lawful basis for B2B outreach to Google Maps businesses.
One honest note: LeadGrid does not guarantee legal compliance for a specific campaign. LeadGrid's data comes only from public business listings; how it is used in outreach is the agency's and client's responsibility.
Frequently asked questions about building agency prospect lists
- Can I build a list for a client in a specific US city, not just a whole state?
- Yes. LeadGrid accepts city-level queries — 'plumbers in Austin TX' or 'lawyers in Brooklyn NY' — and returns results filtered to that geography. You are not forced to pull a whole state and filter manually.
- What happens if a business has no email on Google Maps and no email on its website?
- LeadGrid returns the listing with name, address, phone, and website but leaves the email field blank rather than inventing a pattern. In the LeadGrid analysis of 4261 US local-business listings, 56.5% had no public email — so expect a meaningful portion of any list to have phone-only contact options.
- Do credits expire if I finish one client project and don't need more leads for a month?
- No. Credits purchased on LeadGrid never expire. You can buy a Bulk pack ($79 for 36 credits) today, use 10 credits for one client, and use the remaining 26 credits six months later for a different client.
- Can I push the list directly into a client's HubSpot account?
- LeadGrid's one-click HubSpot integration pushes results as Companies records. Whether you push to your own HubSpot instance and then transfer, or connect directly to a client's instance, depends on how your agency has configured HubSpot access — LeadGrid does not manage multi-client HubSpot permissions.
- Is LeadGrid better than Apollo for agency prospect list work?
- It depends on the client's ICP. If the client sells to named individuals inside companies — SDRs, marketing directors, procurement managers — Apollo's people database is more relevant. If the client sells to local businesses as entities (e.g., a software vendor selling to dental practices), LeadGrid's business-first, no-subscription model is faster and cheaper. See the full comparison at how we compare.
- How large can a single search be?
- A single search can return up to 1,000 results, spending multiple credits automatically based on result volume. One credit covers up to 50 results, so a 200-result search spends 4 credits.
