What problem does it solve? Cold email campaigns fail when lists contain duplicates, unverified emails, bad titles, or off-ICP contacts, burning domain reputation before copy even matters. This Skill scores a lead list before sending so preventable waste is caught in minutes. ## Core Features & Use Cases - Eight-dimension scoring: Grades email verification coverage, duplicate emails, duplicate domains, title relevance, bad-title patterns, catch-all density, ICP fit, and name quality, each on a 0-100 scale. - Letter grade with action items: Produces an A+ to F grade (verification and ICP fit weighted 2x), the top 5 issues to fix, and a pre-send checklist. - ICP comparison: Optionally compares the list against a client-profile.yaml file declaring target job titles, industries, and headcount ranges. - Use Case: After enriching 2,000 leads via an email waterfall, run the scorecard before uploading to Smartlead; if it returns a C due to 12% catch-all addresses and unverified emails, fix those issues and re-run until the grade reaches B. ## Quick Start Ask the AI to run the list quality scorecard on your leads.csv file with your client-profile.yaml ICP file and show the grade and top issues to fix.
