What is Email Extractor
Last reviewed:
A regular expression (regex) is a concise pattern language for matching and extracting parts of text, supported across virtually every programming language.
Email Extractor runs a pragmatic email regex across your input, finds every candidate address, deduplicates them, and returns the result as a clean newline-separated list.
It is commonly used to harvest sign-ups from chat logs, mine support tickets for contacts, and turn CRM exports into mailable lists.
Why use it
- Pull email addresses from meeting notes or raw chat logs.
- Audit leaked datasets for email presence.
- Mine support tickets to build a customer contact list.
- Verify that a page contains a disclosed contact email.
- Produce deduplicated mailing lists from noisy inputs.
Features
- Pragmatic email regex
- Case-insensitive matching, case-preserving output
- Deduplicated output
- Works on HTML, logs, chat transcripts
- Email Extractor never leaves your machine
How to use Email Extractor
- Paste text. Drop any block containing emails.
- Run. Every matching address is extracted and deduped.
- Copy the list. Use the result as a mailing list or audit record.
Example (before/after)
Input
Contact [email protected] or [email protected]; duplicates like [email protected] are deduped.
Common errors
Obfuscated addresses
'foo [at] bar [dot] com' is not matched.
Fix: Normalise obfuscation first with find-and-replace.
FAQ

Yes — case is preserved but exact duplicates are removed.
Does it validate MX records?
No. The tool is pattern-matching only.
Can I paste HTML?
Yes — extraction ignores surrounding tags and attributes.

No — scanning runs entirely in your browser.
