About Extract Emails
Extract Emails scans any block of text and pulls out all valid email addresses using RFC 5322-compatible regex pattern matching. Duplicate emails are automatically removed, and results are presented as a clean, one-per-line copyable list β ready for import into a mailing list, CRM, or spreadsheet.
The extractor works on any text source including newsletters, HTML page source, CSV exports, log files, and plain text documents. It recognizes the full range of valid email address formats including those with subdomains, plus signs, dots, and international TLDs.
All extraction runs locally in your browser with no data sent to any server. This tool is invaluable for building contact lists from exported data, finding email addresses buried in long documents, or deduplicating addresses collected from multiple sources.

Output Formats
Uses an RFC 5322-compatible email regex. Some edge-case addresses with unusual characters may not be detected. Results are case-preserved but deduplicated case-insensitively.
Examples

Troubleshooting
Obfuscated emails like "user [at] example [dot] com" not being detected
Solution
The tool uses a standard email regex and cannot detect human-readable obfuscations. Use the Find & Replace tool to convert these to standard format (replace " [at] " with "@" and " [dot] " with ".") before extracting.
Expecting international domain emails (IDN) to be detected
Solution
Internationalized domain names (e.g., user@mΓΌnchen.de with non-ASCII in the domain) may not be detected by the standard regex. The extractor is designed for ASCII-domain email addresses.
Duplicate emails from different cases appearing in the list
Solution
The deduplication is case-insensitive β user@example.com and User@Example.com are treated as the same address. The first occurrence in the text is kept. If you still see duplicates, they may have different local parts (before the @).
Frequently Asked Questions
Are duplicate email addresses removed?
Yes. The tool automatically deduplicates the extracted list, keeping the first occurrence of each unique email address. Comparison is case-insensitive, so user@example.com and USER@EXAMPLE.COM are treated as duplicates.
What format are the results in?
Results are presented as one email address per line in a text area you can copy directly or download as a .txt file. This format is compatible with most mailing tools and spreadsheet import wizards.
Does it detect emails in HTML source code?
Yes. The regex scans for email patterns regardless of surrounding context, so it will find emails in mailto: links, plain text, comments, and other HTML content.
What email formats does it recognize?
The tool recognizes standard email addresses including those with plus signs (user+tag@example.com), dots in the local part (first.last@example.com), and various TLDs including multi-part TLDs (.co.uk, .com.br).
Can it detect obfuscated emails like "user [at] example.com"?
No. Human-readable obfuscations designed to fool scrapers cannot be detected by a standard regex. Use Find & Replace to normalize these to standard email format before extracting.
Is there a text length limit?
No. The tool processes text of any length locally in your browser. Paste entire pages, log files, or data exports without concern for size limits.
Is my text stored or sent to a server?
No. All extraction runs in client-side JavaScript. Your text is never uploaded, stored, or transmitted to any server or third-party service.
Does it extract emails from within URLs?
Yes. If a URL contains an email address (such as in a mailto: link or a query parameter), the regex will extract it along with all other email patterns in the text.
