Preparing Data for Enrichment
Before enriching your contact database, start with clean, deduplicated data. When consolidating contact data from CRM exports (Salesforce, HubSpot -- CSV), email marketing platforms (CSV), lead gen form submissions (CSV), event attendee lists (CSV), LinkedIn connection exports (CSV), business card scans and legacy databases, upload the files to Email Extractor to extract and deduplicate email addresses across all sources before running enrichment. Enrichment services charge per record or per API call, so enriching duplicate contacts doubles your cost, and enriching invalid email addresses wastes credits on contacts you cannot reach.
