Extract Emails

How Extract Emails works

Extract every email address from a block of text, de-duplicated and sorted. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

What it finds

The pattern matches a local part, an @, a domain and a dot-suffix of at least two letters — the shape of nearly every address in practice. It works across paragraph text, signature blocks and pasted email threads.

Unique mode lowercases every match before de-duplicating, because Alice@Example.com and alice@example.com are the same mailbox in every system that matters.

What it will not find

Addresses written with “at” and “dot” to defeat scrapers, addresses inside images, and anything with an unusual top-level domain shorter than two characters. It also does not validate that a mailbox exists — a well-formed address can still bounce.

It cannot follow mailto: links that use encoded characters without decoding them first.

Using the list responsibly

Extracting addresses from a page you do not own, then mailing them, is unsolicited mail in most jurisdictions and is a data-protection problem under GDPR. Use this on your own exports, your own inbox or content you have the right to process.

The tool does not store anything, but the list it produces may be personal data the moment you save it.
