Email extraction from text is essential for lead generation, contact list building, and data cleaning workflows. This tool scans text, HTML, or raw email content and extracts every email address using pattern matching. It deduplicates the results and outputs a clean CSV with columns for the email address, the source context (surrounding text), and the extraction position. The extractor uses regular expressions to identify email addresses following the RFC 5322 format, handling edge cases like dots in the local part, plus-addressing (user+tag@domain), and internationalized domain names. The tool processes input from pasted text, uploaded .txt files, or HTML content (stripping tags before extraction). All processing runs in your browser, which is important because email extraction inputs often contain sensitive communication data. The resulting CSV is ready for import into CRM systems, email marketing platforms, or deduplication pipelines.

How to use the Email Extractor tool

  1. Load your text: Drag and drop a text or HTML file, choose a file from your file explorer, or paste text directly into the paste area.
  2. Extract emails: Click the "Extract Emails" button to find and deduplicate every email address in the input.
  3. Export results: Copy the extracted emails to your clipboard or download them as a CSV file.

Frequently asked questions

What input formats does the email extractor support?
The tool processes plain text, HTML, and raw email content. HTML tags are stripped before extraction, so email addresses are found regardless of the source format.
How does deduplication work?
The extractor removes duplicate email addresses, preserving the first occurrence and its surrounding context. Case-insensitive matching ensures user@domain.com and User@Domain.com are treated as the same address.
Does it handle internationalized email addresses?
The tool extracts email addresses with internationalized domain names (IDN) using punycode encoding. Standard ASCII email addresses are fully supported.
Can I extract emails from a website URL?
The extractor processes text and HTML input. To extract emails from a website, first use the URL-to-Text tool to fetch the page content, then paste the output into this extractor.
Is the output suitable for email marketing?
The CSV output is a starting point for building contact lists. Always verify email addresses and ensure compliance with anti-spam regulations (CAN-SPAM, GDPR) before sending marketing emails.
