B2b Contact Mining

Find and verify B2B business contacts without buying a database — mine fresh leads from Google, Telegram and Discord, then SMTP-validate every email for a 2–5% bounce rate. Use when the user wants to find business emails or phone numbers, build a cold-outreach lead list, scrape contacts from a company website or a Discord/Telegram community, replace Apollo/ZoomInfo/Hunter, or verify an email address is real — "find b2b contacts", "cold outreach leads", "email finder", "apollo alternative".

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

Define target — ask (or infer): industry, company size, job titles, location.
Search — Google (multiple passes), then Telegram channels and Discord communities if thin.
Extract — names, titles, emails; cross-reference on LinkedIn.
Validate — run the email_validator.py helper (SMTP, 2–5% bounce vs 25–35% for bought DBs). Never send to unverified emails.
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.
