Data Quality

How We Verify Every Record in the MSP List

Our list of managed service providers isn't scraped once and forgotten. Each company in the MSP database passes through a verification cycle: website validation, phone and email checks, service classification (MSP vs MSSP vs IT consultancy), and firmographic enrichment. Records failing verification are flagged and re-checked before appearing in any list of MSP companies in USA that we deliver. The result is a clean, accurate MSP mailing database with 98% deliverability.
