CRM Data Hygiene Playbook

Data decays ~2% a month. This playbook turns cleanup from a once-a-year panic into a quiet routine.

Monthly

  • Verify any contacts added or edited this month.
  • Merge new duplicates flagged by the CRM.
  • Suppress contacts that bounced or unsubscribed.

Quarterly

  • Re-verify the full active database (email + phone).
  • Archive contacts undeliverable for 2+ quarters.
  • Review and standardize field formatting (phone, country, name case).

At point of capture

  • Validate email and phone on form submit via API.
  • Block disposable domains and obvious fakes before they're created.
  • Normalize phone numbers to E.164 on entry.
