Extracting Target Domains from Existing Email Lists

The Reverse Engineering Strategy

Sometimes you have a massive list of email addresses, but you realize you want to run an Account-Based Marketing (ABM) campaign targeting the companies themselves, perhaps via LinkedIn ads or direct mail. You need the domains, not just the emails.

How to Isolate Domains

While you could use Excel formulas, the Website Extractor provides a much faster workflow. Because an email address ([email protected]) inherently contains a domain, our tool can process a list of emails and extract just the clean company URLs.

Filtering the Noise

When extracting domains from an email list, you will inevitably hit personal domains like Gmail, Yahoo, or Outlook. You must filter these out to focus on the B2B corporate domains.

Workflow: First, use the Bulk Email Data Filter to remove personal email addresses from your list. Then, run the cleaned B2B email list through the Website Extractor to get a pristine list of corporate domains.

Activating the Data

With this clean list of corporate domains, you can upload them as a custom audience in LinkedIn Campaign Manager, or feed them into a firmographic tool to analyze the types of companies currently in your database.

Conclusion

Your existing email list is a treasure trove of account data. Extracting the domains allows you to pivot from individual outreach to broad account-level targeting effortlessly.
