The Problem With Raw Lead Lists

Lead lists from scraping and enrichment tools often contain:

• Duplicate rows

• Inconsistent name formatting

• Junk columns

• Invalid or missing emails

• Mixed email providers

• Catch-all domains marked as risky

Sending directly from these lists leads to:

• High bounce rates

• Poor inbox placement

• Inaccurate campaign results
