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.
