List Cleaning and Lead Hygiene

Day 12 of 30 · B2B Sales 2026 Masterclass

Standardize statuses/sources, dedupe, and set DNC rules so the pipeline reflects reality.

Learning Goal

  • Standardize lead statuses and sources.
  • Set dedupe and do-not-contact rules.
  • QA 50 leads and fix issues.

Why It Matters

  • Dirty lists = bad reporting and bad experience.
  • Unified statuses speed reporting and automation.
  • DNC + dedupe reduces slip and spam risk.

Explanation

Status example

  • New, Working, Nurture, Qualified, Disqualified, DNC.

Rules

  • Dedupe: email/domain + name.
  • DNC: bounce/spam/legal request.
  • Source codes: outbound, inbound, partner, event, referral.

Examples

Good: Status unified, duplicates flagged, DNC list maintained.

Bad: Duplicates, mixed status names, no DNC.
