Preparing Prospect Lists for These Tools

All three platforms import contacts from CSV files. Before importing, upload your prospect files (CSV exports from LinkedIn, scraped directories, CRM exports, purchased lists) to Email Extractor to extract and deduplicate email addresses. This prevents importing duplicate contacts that would receive the same sequence multiple times (wasting send credits on per-email pricing) and ensures your campaigns start with clean data.
