Five ways to fix your data
Pick the service that matches your gap
Missing fields, outdated contacts, or a list that needs deeper detail, each service below solves a different data problem. Most clients only need one or two of these at a time.
B2B databases don't decay evenly. A CRM might have accurate names and companies but no working phone numbers. A trade show list might have emails but nothing else. A list bought years ago might just be wrong, addresses that no longer exist, contacts who've since changed jobs. Data Mappers' five data services exist because "fix the data" isn't one job, it's five different jobs depending on what's actually broken.
All five draw on the same 160M+ record database and the same verification standard, 95%+ accuracy with real-time email checks, so switching between services (or combining them) doesn't mean switching data quality.
