B2B Contact Mining

Find and verify B2B business contacts without buying a database. The agent mines fresh leads from Google, Telegram, and Discord — then SMTP-validates every email before it goes into a cold-outreach list. Free, self-hosted, no vendor lock-in.

When to Use

  • The user wants to find B2B business emails or phone numbers.
  • Building a cold-outreach / lead-gen list from scratch.
  • Replacing Apollo, ZoomInfo, Hunter, or a resold contact database.
  • Mining leads from Telegram channels or Discord communities.
  • Verifying that a list of emails is real before sending.

Don't use for: buying or reselling contact data, or non-B2B consumer leads.

Prerequisites

  • The agent's own web-search tool for Google / Telegram / Discord.
  • The SMTP validator needs dnspython — install deps from requirements.txt (see README).
  • Optional: TAPAC API key (https://tapacapi.com/get-key) to automate the pipeline as an MCP server.

How to Run

  • SMTP-validate a list of emails with the email_validator.py helper in scripts/ — it prints VALID / INVALID / UNKNOWN per line.
  • Ready prompts for any agent: prompts/ai-agent-prompts.md.
  • The agent does the searching itself; this skill supplies the methodology + the validator.

Procedure

  1. Define target — ask (or infer): industry, company size, job titles, location.
  2. Search — Google (multiple passes), then Telegram channels and Discord communities if thin.
  3. Extract — names, titles, emails; cross-reference on LinkedIn.
  4. Validate — run the email_validator.py helper (SMTP, 2–5% bounce vs 25–35% for bought DBs). Never send to unverified emails.
  5. Output — structured data (name, title, company, email, source, verification status) as JSON / CSV / CRM.

Pitfalls

  • Never buy a contact database — 23% of contacts change jobs annually, 40% of emails die within 2 years.
  • Always SMTP-validate before sending; unverified sends destroy sender reputation.
  • Never invent contacts — return only what was actually found.
  • Scraping public company / social data is legal (hiQ Labs v. LinkedIn, 2022); stay off private or credential-gated data.

Verification

  • Every returned contact carries a source and a verification status.
  • Emails passed through email_validator.py before outreach.
  • The methodology matches AGENTS.md and README.md.
