Lead Enrichment Guide

By Abdul Sami, GTM Engineer · 6 min read · Last updated

Lead enrichment is adding missing data (verified email, phone, title, firmographics, tech stack) to a raw contact. The efficient pattern is a waterfall: try the cheapest provider first, fall through to others on a miss, and only pay for verified results. Enrich what you'll act on this quarter data decays 2–3% monthly.

Why waterfalls win

Single providers match 50–70% of a typical list. Chaining 3–5 providers in sequence pushes coverage to 85–95% while you only pay for the successful hit. In Clay this is a native pattern; outside Clay it's built with n8n or scripts.

Order operations by cost

  • Free checks first: dedupe, syntax, MX.
  • Cheap enrichments second: company data, titles.
  • Expensive lookups last: verified emails, mobiles only on surviving rows.

Keep it fresh

Enrichment is not one-and-done. Job changes alone invalidate ~30% of contact data per year. Re-verify active sending segments quarterly.
