PRACTICAL GUIDE

How to Clean B2B Leads in 60 Seconds

📅 March 2026 • ⏱ 4 min read • By Leedrush Team

Every SDR team wastes 30-40% of their time on bad data — invalid emails, duplicate records, and unscored leads. Here's how to fix that in under a minute.

The Problem: Bad Data Kills Pipeline

A typical B2B lead list from a vendor like Apollo, ZoomInfo, or a conference download contains:

  • 15-25% invalid emails — outdated domains, typos, catch-all addresses
  • 10-20% duplicates — same person, different spellings or sources
  • 0% quality score — no way to prioritize who to contact first

Loading this raw data into your CRM or sequencing tool means your SDRs waste 2-3 hours daily on dead leads.

The Solution: 3-Step Lead Cleaning

Step 1: Upload Your CSV (5 seconds)

Drag and drop your lead file. Any format works — CSV, XLSX, JSON. Leedrush auto-detects columns: email, name, company, phone, title, website.

Step 2: Watch the Engine Work (45 seconds)

The enrichment engine runs 7 validation layers in parallel:

  1. Email validation — SMTP handshake + DNS check + pattern matching
  2. Phone validation — format check + carrier lookup
  3. Deduplication — fuzzy matching across name, email, company, and domain
  4. Data enrichment — fills in missing title, company size, industry, LinkedIn URL
  5. Lead scoring — AI-powered quality score from 0-100 based on data completeness and signals
  6. Domain check — identifies disposable, catch-all, and role-based addresses
  7. CRM readiness — standardizes formats, normalizes fields

Step 3: Export Clean Leads (10 seconds)

Download the enriched CSV — only qualified leads. Every record has a quality score, validated email, and enriched company data. Load directly into Salesforce, HubSpot, or your sequencing tool.

💡 Pro Tip: Focus your SDR team on leads with a quality score of 70+. These typically have 3x higher reply rates than unscored leads.
