How to enrich a stale CRM with fresh contact + firmographic data

Use cases·1 min read·Updated 2026-05-13·4 sections

CRMs decay. Emails bounce after 12-18 months as people change jobs. Industry data goes stale. Decision-makers leave. Re-enriching saves campaigns and improves data hygiene.

01

Step 1: export your CRM list

Get a CSV with name, company, email, role per row.

Step 2: verify emails (cheapest win)

Kavex Email Verifier on the entire list. Flags bounces + catch-alls. About 20-40% of an 18-month-old list will fail verification.

Step 3: refresh firmographics

For each company domain, Kavex Tech Stack Detector + LinkedIn Companies. Updates industry, size, tech, headcount.

04

Step 4: replace people who left

For verified-failed rows, run LinkedIn Company People at the same company with the original role → find the new person in that seat.
