A reusable enrichment table for event leads, and contact data on a re-verification schedule

The problem

The play

1. 1
   A reusable enrichment table, not a per-event scramble

   Built a reusable table that waterfalls work-email and contact lookups across a seven-provider chain before validation, then syncs enriched leads straight to CRM campaigns. The waterfall matters more than any single provider: each one is tried in turn and the first confident match wins, so coverage comes from the chain rather than from betting on one vendor.

2. 2
   Adapt the output to the downstream system

   When routing later moved onto a dedicated platform, the same table was reconfigured to a clean export instead of a direct sync, so the enrichment investment survived a change in the system downstream of it.

3. 3
   Validate contacts phase by phase, starting where revenue is

   Ran a phased lead-and-contact validation that began with the largest accounts rather than attempting the whole database at once: pulled contacts into the enrichment platform and validated professional-profile and email data to flag people who had left the company.

4. 4
   Write the answer back as fields, not a spreadsheet

   Added 'no longer at company', 'verified contact data' and enriched-phone fields in the CRM so the validation result lives on the record and is usable in segmentation and routing, rather than dying in an export.

5. 5
   Put re-verification on a schedule

   Built a recurring report so contacts get re-checked on a cadence, instead of decaying silently until the next campaign underperforms and someone goes looking for why.
