Extract Email Addresses

In short Extracting email addresses scans text or HTML for anything matching the address pattern, removes duplicates and returns a clean list. It works on pasted web pages, on email headers with long recipient lists, and on documents where addresses are scattered through prose. The pattern used is deliberately practical rather than exhaustive: the full specification for a valid address is famously permissive and allows quoted strings and comments that no real address uses, so matching it exactly finds more false positives than real addresses. What you get here is what people actually type. Two caveats. Addresses written to defeat scrapers — "name at example dot com" — are not matched, by design. And obfuscated HTML where the address is assembled by JavaScript will not contain it in the text at all. The legal point is the one that matters most: extracting addresses is not the same as being allowed to use them. Bulk emailing addresses collected this way is unlawful under GDPR, CAN-SPAM and equivalent rules in most countries, whatever the addresses were extracted from.
