Extract Emails From Text is a free browser tool that pulls email addresses out of any block of text and turns them into a clean, deduplicated, exportable list. It is operated by Neurohain, and you can reach us at info@neurohain.com.

Why we built it

The tool exists because of a job that kept recurring and kept being annoying: someone hands you a document — a conference roster, a CRM export, a forwarded thread with sixty people on it, a directory page — and you need the email addresses out of it, without the commas, angle brackets, duplicates and shared inboxes that came along for the ride.

The existing options were unsatisfying in the same way. Most were server-side, which meant uploading a client’s prospect list to an unknown third party to save ten minutes. Several capped you at a few hundred characters unless you registered. A few were plainly harvesting the pasted text. For anyone handling contact data under a confidentiality obligation, none of that is acceptable — and none of it is technically necessary, because the problem is a pattern-matching problem that a browser can solve instantly on its own.

How it works, and what that means for your data

Extraction runs as JavaScript inside your own browser. The text you paste is processed on your device, is never transmitted to our servers, is never written to a database, and is never logged. This is not a policy promise you have to take on trust — it is an architectural fact you can verify in about fifteen seconds: open your browser’s developer tools, switch to the Network tab, and extract a list. No request carrying your text is made, because there is no endpoint for one to go to.

The practical upside beyond privacy is speed. There is no upload, no queue and no processing screen, so results and metrics recalculate on every keystroke even at the full 50,000-character input limit. The trade-off is that the work is bounded by your device rather than by a server, which is why very large archives are better handled in batches.

What we hold to

  • Your data stays yours. No uploads, no accounts required, no analytics on the content of what you paste.
  • The free tier is genuinely useful. Every filter, every metric and unlimited extraction are free. The paid tier adds structured spreadsheet exports; it does not unlock the tool itself.
  • We say what the tool cannot do. Extraction confirms that an address is correctly formatted. It does not confirm that a mailbox exists, and we would rather tell you that plainly than let you find out through a bounce rate.
  • Ads stay out of the way. No interstitials, no pop-ups, nothing covering the tool or the content, and no ad placed where it could be mistaken for a control.

How the site is funded

Three ways, all of which we would rather state openly than have you work out.

Advertising. Display ads appear alongside the tool and beneath the guides. They are clearly separated from the interface and never sit between you and something you were trying to do.

A paid tier. Pro adds structured CSV and XLSX exports that split each address into Email, Domain and TLD columns, and removes the export cap. It is a convenience upgrade for people cleaning lists regularly, not a paywall around the core tool.

Affiliate links. The guides and the tool link to email verification and outreach platforms, and some of those links earn us a commission. They are marked as sponsored in the markup. We only list tools we would use on our own lists, and the recommendation to verify a list before sending would be the same advice if it paid us nothing — a 20 percent bounce rate is a real problem regardless of who benefits from solving it.

Who it is for

Mostly three groups. Sales and SDR teams turning event lists and directory pages into prospect lists. Recruiters pulling candidate contacts out of bulk applicant exports and long threads. Marketing and operations people cleaning a list before it reaches a sending platform, where deduplication and role-account removal directly protect sender reputation.

If you are doing any of that, the guides are written for you: they cover where addresses hide in each kind of source, the order to run cleaning steps in, what the address format actually permits, and the rules that apply once you start sending.

Getting in touch

Bug reports, an address format the parser mishandles, a source type it cannot cope with, or a billing question — all welcome. Write to info@neurohain.com or use the contact page. Reports that include a small sample of the text that broke it get fixed fastest.
