Email Extractor
Pull email addresses out of any text, de-duplicate them and group by domain.
What is Email Extractor?
The Email Extractor pulls syntactically valid addresses out of any pasted text — HTML source, log output, CSV, JSON, an email body — de-duplicates them and groups them by domain.
The addresses found are only syntactically valid; nothing checks that they exist or that the domain accepts mail. Click a domain in the results to audit its email security configuration.
Everything runs in your browser. The tool is for extracting addresses from data you already hold — log analysis, data cleanup, system migrations.
Frequently Asked Questions
8 questionsIs my text sent anywhere?
No — extraction runs entirely in your browser. Pasted text never reaches a server and isn't stored.
Which formats can I extract from?
Any: HTML source, CSV, log output, an email body, JSON or plain text. The tool scans the whole input for the email pattern and de-duplicates what it finds.
Are the addresses found valid?
Only syntactically. Nothing checks that the address exists, that the mailbox is open, or that the domain accepts mail. Click a domain in the results to run an email security check against it.
Can I use this list for bulk email?
Sending to addresses harvested without consent is unlawful under GDPR and similar regimes, and gets your domain blocklisted. This tool is for pulling addresses out of data you already hold — log analysis, data cleanup, migrations.
Does it handle very large text?
As long as it fits in browser memory — log files of a few megabytes are fine. Much larger inputs may make the page unresponsive; split the file in that case.
Can I export as CSV?
Copying the addresses line by line into a text file gives you a single-column CSV. A JSON download is also available, and the per-domain table has its own copy buttons.
Can I verify the addresses actually work?
This tool only checks format. To see whether the domain accepts mail at all, click a domain in the results and run the email security check — no MX means delivery is impossible anyway.
Are addresses inside comments or obfuscated ones found?
Every address written plainly in the text is found, including inside HTML comments. Deliberate obfuscation like "name [at] domain [dot] com" doesn't form a standard email pattern and isn't matched.
