Extract Emails

The Extract Emails tool scans a block of text and extracts every email address it finds, outputting them as a clean list — one per line. It uses a robust regex pattern that handles standard email formats including subdomains, plus-addressing (name+tag@domain.com), and quoted local parts.

Email addresses are embedded in all kinds of unstructured text: meeting notes, email threads, web page source, CSV exports, log files, and scraped content. Manually hunting for addresses in a wall of text is slow and error-prone. This tool isolates them in under a second.

How to use it: paste any block of text — HTML source, plain text, a full email thread, a log file — into the input. The tool extracts all strings that match the RFC 5321 email address format and outputs them as a deduplicated list. Toggle "Include duplicates" to keep repeats if you need to count occurrences.

Privacy: this tool is often used to process content that contains other people's email addresses. Because it runs locally in your browser, the extracted addresses are never transmitted to a server, logged, or stored. Useful for handling sensitive contact lists or legal documents.

Regex note: the extractor uses a pattern that catches the vast majority of real-world email addresses without producing false positives from obviously non-email strings. It correctly handles domains with multiple levels (user@mail.example.co.uk) and ignores malformed strings that lack a valid TLD.
