Email Validator

Email Validator

Finds and validates email addresses using Snov.io via Chrome DevTools MCP. Takes LinkedIn profile URLs from decision-maker-finder and returns verified emails. Minimum 3 verified emails per company required; flags RED if fewer.

Prerequisites

• agency.config.json populated with tools.email_validation
• Snov.io logged in on Chrome Beta
• Chrome DevTools MCP available (mcp__chrome-devtools__*)
• LinkedIn profile URLs for contacts (from decision-maker-finder)

Phase 0: Intake

Read agency.config.json:

• tools.email_validation.tool -- must be "snovio"
• tools.email_validation.access -- must be "chrome_devtools"
• tools.browser_automation -- Chrome DevTools MCP config

Accept parameters:

1. List of contacts with LinkedIn profile URLs (from decision-maker-finder output)
2. Company name for each contact (for grouping and threshold checking)

Phase 1: Navigate to Snov.io

Using Chrome DevTools MCP:

1. mcp__chrome-devtools__navigate_page to Snov.io dashboard
2. Verify logged-in state (check for user avatar or dashboard elements)
3. If not logged in: STOP and report "Snov.io login required in Chrome Beta"
4. Navigate to the email finder / LinkedIn lookup section

Phase 2: Find and Validate Emails via LinkedIn Profile URLs

CRITICAL: ALWAYS use Snov.io LinkedIn Search (app.snov.io/linkedin/search) with the person's LinkedIn profile URL. NEVER guess email patterns from domain names. Snov.io returns the actual verified email tied to the LinkedIn profile.

For each contact:

Chrome DevTools MCP Workflow (Single Lookup):

1. mcp__chrome-devtools__navigate_page → https://app.snov.io/linkedin/search
2. mcp__chrome-devtools__fill → paste full LinkedIn profile URL (e.g. https://www.linkedin.com/in/chris-ferguson-80b98b79)
3. mcp__chrome-devtools__click → "Find email" / search button
4. mcp__chrome-devtools__wait_for → results to load (email found or not found)
5. mcp__chrome-devtools__take_snapshot → read verified email from results

Snov.io finds the real email from the LinkedIn profile and returns:

• Email address (the actual email, not a guess)
• Verification status (valid, invalid, catch-all, unknown)
• Green dot = verified, Gray dot = not found

For Multiple Contacts (Bulk):

Use Snov.io Bulk LinkedIn Search:

1. Navigate to bulk search or use the LinkedIn Search page repeatedly
2. Paste each LinkedIn URL one by one
3. Collect all verified emails before sending any outreach

NEVER DO THIS:

• Do NOT guess emails from domain patterns (e.g. firstname@domain.com)
• Do NOT use Email Search with name + domain as primary method
• Do NOT send emails without Snov.io verification first
• Do NOT use Domain Search to infer email patterns and construct addresses

Phase 3: Process Results

For each contact, record:

{
  "name": "Jane Doe",
  "company": "BrandX",
  "linkedin_url": "https://linkedin.com/in/janedoe",
  "email": "jane@brandx.com",
  "email_status": "valid",
  "email_type": "professional",
  "source": "snovio"
}

Classification handling:

Phase 4: Company Threshold Check

For each company, verify minimum email coverage:

• Count verified (valid + catch-all) emails per company
• Minimum threshold: 3 verified emails per company
• If >= 3 verified: company is GREEN
• If < 3 verified: company is RED

For RED companies:

1. FLAG as RED on CRM sheet (visual indicator)
2. Note in CRM: "Low email coverage - [N] verified emails. Prioritize LinkedIn outreach."
3. Still proceed with available emails, but prioritize LinkedIn/Instagram channels

Phase 5: Update CRM

Write validation results back to CRM via crm-writer:

• Update email and email_status columns for each contact
• Flag RED companies with a visual indicator
• Update lead stage from RESEARCHED to email-validated

No approval gate. Results are written directly.

Phase 6: Summary

Email Validation Complete (Snov.io):
- Contacts processed: N
- Emails found: N
- Valid: N (X%)
- Catch-All: N (X%)
- Invalid: N (X%)
