SalesQL CSV Enrichment bulk-appends verified emails, phone numbers, and firmographics to uploaded contact files.
CSV Enrichment is the file-based data enrichment offering from SalesQL, available at salesql.com/csv-enrichment. Users upload a CSV and the service cross-references names and companies, or lists of profile URLs, against its B2B database to append verified email addresses, phone numbers, and firmographic details to each row.
Enriched contacts import directly into a SalesQL folder to keep existing lists current, and the feature ships with paid plans without requiring code. Sales, marketing, and recruiting teams use it to refresh legacy contact files before campaigns.
