Email Domain Extractor parses email addresses from any text and isolates the domain portion (everything after the @), producing a deduplicated list of unique domains. It handles various email formats including display names ('John Doe <[email protected]>'), mailto: links, and addresses embedded in unstructured text. The tool provides domain frequency counts, groups addresses by domain, and can identify the organizational domains by stripping subdomains (mail.company.com becomes company.com).
Email marketers optimizing deliverability, sales teams building prospect lists, and security analysts investigating email sources. The tool runs entirely in your browser — your data never leaves your device.
