From addresses to organizations in one step

Every email address carries its organization in plain sight: everything after the @. The Domain Extractor pulls those domains out, deduplicates them, ranks them by frequency, and hands you a clean list — the fastest way to see which companies, universities, and providers are actually represented in your data.

Sales teams use it to group leads by account. Analysts use it to profile list composition before campaigns. Developers use it to audit which mail infrastructure their user base runs on. All it takes is pasting addresses; ranking and counting happen live as you type.

Want the reverse direction — building address lists from raw text? Start at the Email Extractor, then hop here; both tools share the same local-first engine.

FAQ

Domain Extractor questions

What exactly gets extracted?

The unique set of domains from your email addresses — the part after the @ sign, including subdomains — with occurrence counts so you can see which companies or providers dominate the list.

Are provider domains separated from company domains?

Yes, visually: counts tell you instantly that gmail.com appearing 400 times is very different from acme-corp.com appearing 3 times. For a deeper brand-level grouping (Google vs Microsoft vs Apple families), use the Email Analyzer.

Can I export just the domain list?

Yes — the result panel lists one domain per line ready to copy, and the download gives you a .txt file of unique domains with counts stripped out.

Why extract domains from emails?

Domain lists power company-based segmentation, competitor research, MX-configuration audits, blocklist management, and quick estimates of how much of a list sits on corporate infrastructure versus consumer free-mail.
