How to Use the Company Email Domain Extractor

Account-Based Marketing (ABM) strategies rely on mapping enterprise target accounts rather than individual employee personal inboxes. Our Email Domain Extractor processes large lead lists to isolate unique corporate website domains, enabling B2B sales teams to discover prospective client enterprises.

  1. Paste your raw list of professional email contacts or unordered communication transcripts into the left workspace.
  2. Enable 'Filter Public Free Webmail' if you wish to exclude generic domains like gmail.com, yahoo.com, hotmail.com, and outlook.com.
  3. Select deduplication filtering so that multiple employees sharing an identical employer domain yield only one company record.
  4. Click 'Extract Corporate Domains' to harvest the targeted corporate web URLs.
  5. Copy your purified domain list to import directly into LinkedIn Sales Navigator, ZoomInfo, or Apollo account target matrices.
