How to read our quality stats
Here is how we measure the quality of our data:- Email re-verification: The share of distinct valid email addresses with a verification date within the stated window. The 30-, 45-, and 60-day windows are cumulative.
- Profile dates: A recent verification timestamp should reflect a successful retrieval of current profile information. When that cannot be substantiated, the corrected date uses the last known profile-change date. Record update dates and successful profile observations measure different things.
- Company accuracy: The share of company data verified by trusted sources within the past 90 days.
