Lead Scraping and Enrichment Pipeline

\n

Last updated: 2026-05-12

\n

A cold outreach system is only as good as the list it runs on. Unverified numbers and bad emails are the #1 reason reply rates collapse. This pipeline covers how to build a verified, enriched list ready for cold SMS or email.

\n
\n

Step 1 — Define the Target

\n

Before scraping anything, answer:

\n\n

Defining filters before scraping prevents wasted enrichment budget on bad-fit prospects.

\n
\n

Step 2 — Scraping Sources

\n

Google Business Profile (GMB) — Primary

\n

Tool: Outscraper (outscraper.com)

\n

Scrapes GMB listings by niche + geo. Returns:

\n\n

Best for: Local service businesses. Coverage is near-complete for businesses with a GMB listing.

\n

Outscraper settings:

\n\n
\n

LinkedIn — B2B Prospecting

\n

Tool: Apollo.io or Sales Navigator export + PhantomBuster

\n

Best for commercial service targets (commercial cleaning, IT services, commercial HVAC). Returns:

\n\n

Apollo gives 50 free credits/month. For volume, use the paid tier or PhantomBuster LinkedIn scrapes.

\n
\n

Directories — Secondary

\n

For niches with strong directory presence:

\n\n

Directory scraping gives you name, phone, website, and review count. Use for backfill when GMB returns are thin.

\n
\n

Step 3 — Enrichment

\n

Raw scraped data is incomplete. Enrich before sending.

\n

Phone Verification

\n

Tool: Twilio Lookup API or NeverBounce Phone

\n

For each phone number in the list:

\n\n

Remove all numbers that return as disconnected or invalid. Do not send to bad numbers — it burns your sending reputation with carriers.

\n

Cost: ~$0.005 per lookup with Twilio.

\n
\n

Email Verification

\n

Tool: NeverBounce, ZeroBounce, or Hunter.io Verify

\n

For each email:

\n\n

Send only to Valid and Catch-All (with a suppression layer for bounces).

\n
\n

Owner Name Enrichment

\n

Raw GMB scrapes return business name, not owner name. For personalized outreach, look up owner names through:

\n\n

Owner first name alone is sufficient for SMS personalization. Full name for email.

\n
\n

Website and GMB Signal Enrichment

\n

After scraping, run each business through a quick audit signal check:

\n\n

Add these signals to the spreadsheet as columns. They become the hooks for your cold outreach copy.

\n
\n

Step 4 — Deduplication and Cleaning

\n

Before loading the list into your sending tool:

\n
    \n
  1. Deduplicate by phone number — remove any number appearing more than once
    2. \n
  2. Deduplicate by business name + city — same business listed twice from different scrape sources
    3. \n
  3. Remove clients you already work with — pull your current client list and suppress
    4. \n
  4. Remove prior contacts — cross-reference with your CRM for anyone you've already reached out to in the last 90 days
    5. \n
  5. Remove DNC numbers — for SMS: check against your internal DNC list and any purchased DNC registry (Syniverse or similar)
    6. \n
\n
\n

Step 5 — List Segmentation

\n

Segment before sending. Do not send one undifferentiated blast.

\n

Example segments for a GMB-targeted list:

\n

| Segment | Criteria | Offer Angle |\n|---|---|---|\n| No website | Website field blank in GMB | \"You have no website — we can fix that in 7 days\" |\n| Low reviews | Under 10 reviews | \"Your competitors have 80+ reviews — here's how to catch up\" |\n| Not in map pack | Competitor check shows they're not ranking | \"You're invisible on Google Maps for [keyword] — we fixed this for 3 others in [city]\" |\n| Old website | Website created before 2020 | \"Your site is hurting your GMB ranking — here's why\" |

\n

Segmenting allows you to write one message per segment rather than one generic message for all.

\n
\n

List Size Targets

\n

| Channel | Minimum List Size | Why |\n|---|---|---|\n| Cold SMS | 500 per send | Need volume to generate meaningful reply rates |\n| Cold email | 200 per send | Lower reply rates, need more volume per outcome |\n| Cold call | 50–100 per day per setter | Manageable dials with quality conversations |

\n
\n

Tools Summary

\n

| Step | Tool | Cost |\n|---|---|---|\n| GMB scraping | Outscraper | ~$0.001/record |\n| LinkedIn scraping | Apollo + PhantomBuster | $49–$99/mo |\n| Phone verification | Twilio Lookup | ~$0.005/number |\n| Email verification | NeverBounce | ~$0.008/email |\n| Owner enrichment | Apollo | Included in plan |\n| CRM dedup | GHL | Included |
