Builds a list of verified business emails from Google Maps, Google SERPs, or a user-supplied URL list. Verification happens inside the same Apify run — no third-party verifier needed. Use when user asks to find verified emails, build a leads list, scrape emails from Maps or SERP, verify emails for a URL list, or find an Apollo / Hunter alternative.

Verified Email Finder

Return a list of verified business emails by routing the user's input to the right Apify Actor and turning on the leads enrichment + email verification add-ons in a single run. No third-party verifier (Hunter, NeverBounce, Apollo) needed — verification happens inside the same Actor run.

Prerequisites

(No need to check it upfront)

The skill supports two execution paths. Pick the one that matches your environment — Steps 4 and 5 show commands for both.

MCP path (default in Claude sessions, recommended). If the Apify MCP server is connected, no setup is needed — auth runs through the user's Apify account. Use the call-actor and get-dataset-items MCP tools.

Script path (CLI / scheduled / non-Claude execution). Requires:

  • .env file with APIFY_TOKEN
  • Node.js 20.6+ (for native --env-file support)

Workflow

Copy this checklist and track progress:

Task Progress:
- [ ] Step 1: Collect the six required anchor inputs
- [ ] Step 2: Route to the correct Actor (confirm if ambiguous)
- [ ] Step 3: Build the Actor input (verification always ON)
- [ ] Step 4: Run the Actor and wait
- [ ] Step 5: Apply the result-scope filter, deduplicate, and render

Step 1: Collect the Six Required Anchor Inputs

Ask all six as one block before any Actor call. Don't bundle Actor-specific optional fields (country code, language, max pages) into this round — surface those as follow-ups.

  1. What do you have to start with? — location query / SERP keyword / URL list. This drives the routing decision.
  2. The actual input — the location string, the keyword(s), or the URLs themselves.
  3. Department filter — one or more of: c_suite, product, engineering_technical, design, education, finance, human_resources, information_technology, legal, marketing, medical_health, operations, sales, consulting. Default is any (leave the array empty), but ask every time.
  4. Max contacts per domain / business — passed as maximumLeadsEnrichmentRecords. Default 3, but ask every time.
  5. Output format — CSV or JSON. Ask every time.
  6. Result scope — which leads to keep in the deliverable. The Actor always runs the same way (verification always on); this only controls post-run filtering. Pick one:
    • verified-only (default) — only leads with emailVerification.result == "ok". Safest for cold email.
    • verified-plus-catchall — ok plus catch_all. Catch-all is often deliverable but unprovable.
    • all-emails — any lead with a non-empty email, regardless of verification.
    • with-phone — any lead with a non-empty phone number, regardless of email status. Use for call campaigns.
    • everything — every lead the Actor returned, even incomplete ones.

Step 2: Route to the Correct Actor

Inspect anchor #1 and pick the Actor.

User has to start withActor IDUse when
Location + business type ("dentists in Berlin")compass/crawler-google-placesLocal leads list from Maps listings; best when user wants address / phone / hours too
Keyword / search query ("best CRM software")apify/google-search-scraperContacts from whichever sites Google ranks for a topic
Pre-existing URL list (pasted, file path)vdrmota/contact-info-scraperUser already has domains; cheapest route since no discovery step

All three Actors share the same three add-on fields, so verification behavior is identical across routes.

Decision examples

User saysRoute
"Dentists in Munich" / "Lawyers in Prague"Maps
"Marketing contacts at the top results for 'AI agent builder'"Search
"Find emails for these 5 URLs: acme-co.example, demo-co.example..."URL list
"Find HR contacts at Fortune 500 companies"Ask: SERP for "Fortune 500 HR" or a URL list?
"Find contacts at SaaS companies in Berlin"Ask: Maps for "SaaS companies in Berlin" or SERP for "SaaS companies Berlin"? Maps works best when businesses are Google-Maps-listed.
(User pastes both a SERP keyword AND a URL list)Ask: run one route, the other, or both as separate deliverables?

Ambiguity rule: if anchor #1 is unclear, ask one follow-up before running. Never burn Actor compute on a guessed route.

Mixed deliverables: if the user explicitly asks for two routes in one deliverable, run both Actors and concatenate. The Source column makes the mix clear; dedupe by email across the combined output.

Step 3: Build the Actor Input

Always set these three fields, regardless of which Actor is selected.

FieldValue
maximumLeadsEnrichmentRecordsanchor #4 (default 3, min 1)
leadsEnrichmentDepartmentsanchor #3 as array, or [] if "any"
verifyLeadsEnrichmentEmailstrue (always) — guard rail, never set to false

Full per-Actor input parameters and example payloads are in reference/apify-actor-usage.md.

URL-list pre-validation: before submitting URLs to vdrmota/contact-info-scraper, parse each one and check it is http/https and parseable. Skipped entries must appear in the output as skipped — invalid URL, never silently dropped.

Step 4: Run the Actor

Maps and SERP runs with leads enrichment can take several minutes per query. Raise the timeout for large jobs.

MCP path (default in Claude sessions):

Call the call-actor tool:

  • actor: one of the three Actor IDs (compass/crawler-google-places, apify/google-search-scraper, vdrmota/contact-info-scraper)
  • input: the JSON payload from Step 3
  • callOptions: {"timeout": 1800, "memory": 4096} for a generous budget

The tool returns runId and datasetId. If status is still RUNNING, poll with get-actor-run (waitSecs up to 45) until SUCCEEDED. Capture both IDs for the run_metadata.json sidecar.

Script path (CLI / scheduled use):

node --env-file=.env ${CLAUDE_PLUGIN_ROOT}/reference/scripts/run_actor.js \
  --actor "ACTOR_ID" \
  --input 'JSON_INPUT' \
  --output YYYY-MM-DD_verified-emails.csv \
  --format csv \
  --timeout 900

Use --format json for JSON. The script writes the raw dataset to disk; Step 5 still applies the spurious-match + scope filters on top.

Step 5: Filter, Deduplicate, and Render

Pull the dataset:

  • MCP path: call get-dataset-items with the datasetId from Step 4. Use the fields parameter (e.g., title,searchString,countryCode,city,address,phone,website,leadsEnrichment) and clean: true to keep the response small. For datasets that still exceed the response cap, fetch directly via curl https://api.apify.com/v2/datasets/<id>/items?fields=...&clean=true and pipe through jq.
  • Script path: the raw dataset is already on disk in the file from Step 4.

Each record contains business fields plus a leadsEnrichment array (Maps, SERP) or top-level lead fields (URL list). Each lead has a departments array, a companyWebsite, and an emailVerification object with result (ok / invalid / disposable / catch_all / unknown / error) and quality (good / risky / bad).

  • Spurious-match filter (mandatory, always on). Apply this first, before any other filter. The lead-enrichment service can return global-fallback leads when no local match exists (real case observed: a single US-zoo CFO whose companyWebsite=zoo.org was attributed to 8 unrelated Polish zoos because the matcher latched onto the zoo substring). Drop any lead whose companyWebsite hostname doesn't equal the source URL's hostname (strip https?://, leading www., anything after /; lowercase). Count drops in run_metadata.json and call them out in the deliverable header if non-zero.
  • Filter by result scope (anchor #6). Applied second.

    ScopeRow-keep logic
    verified-onlyemailVerification.result == "ok"
    verified-plus-catchallemailVerification.result in {"ok", "catch_all"}
    all-emailsemail is non-empty (any result, including missing verification)
    with-phonephone (or company phone) is non-empty (regardless of email)
    everythingkeep every lead, no filter
  • Dedupe: group by lowercased email; keep the first occurrence and merge Source Query or URL if the same email appears from multiple sources. For with-phone rows that have no email, dedupe by lowercased phone instead.
  • Empty-result surfacing: if the department filter (anchor #3) produces zero leads for a given domain, include a row for that domain with Email = "" and Email Verification Status = "no leads matched filter". Do not silently drop it. This is separate from the result-scope filter above — empty-domain rows are inserted before scope-filtering and always shown.

Output row schema (16 columns, including Departments) and per-format rendering details are in reference/output-formats.md.

Worked Examples

  • Maps: examples/example-maps-input.md
  • SERP: examples/example-search-input.md
  • URL list: examples/example-url-list-input.md

Quality Rules (always enforce)

  • Guard rail: never submit a run with verifyLeadsEnrichmentEmails: false.
  • Provenance & traceability: populate the Source column on every row; carry Apify runId + datasetId in run_metadata.json.
  • No fabrication: missing dataset fields stay blank.
  • Deliverable header transparency: state the active result scope and the spurious-match drop count; offer to re-render under a different scope.
  • Ambiguity confirm: if anchor #1 is unclear, ask before running.

Cost & Pricing

Email verification is charged only for decisive results (ok / invalid / disposable); catch_all / unknown / error are free. Leads enrichment is charged per successfully extracted lead. Check the Apify console for live rates (they vary by subscription tier and change over time).
