Example Use Cases: What Teams Use Lead List Cleaning Services For

Scraped Data Cleanup

A tech company purchased a scraped list of leads for their product and discovered 35% were invalid or missing email addresses. We ran verification, removed duplicates, and enriched the remaining records with decision-maker titles and company data-enabling effective lead generation.

CRM Field Cleanup

A mid-market SaaS business wanted to generate leads through account-based marketing, but their CRM was riddled with outdated contacts and mixed formatting. We standardized the data, enriched contact fields, and made it ABM-ready.

Multi-Source Merge & Attribution

One B2B client had event signups, webinar attendees, and ad leads from multiple sources. We helped them merge all records, add campaign tags, and create a deduped list of leads for multi-touch outreach.
