Frequently Asked Questions
What is an email extractor?
∨
An email extractor scans text and pulls out every valid email address it finds. Instead of copying addresses one by one from documents, HTML code, or logs, you paste the whole text once and get a clean list of addresses you can copy, deduplicate, and export.
Does it work with HTML source code?
∨
Yes. Paste the raw HTML source (mailto: links, footer signatures, contact blocks) and the tool extracts every address, ignoring the surrounding markup. It also handles plain text, CSV exports, email headers, and log files.
What counts as a valid email address?
∨
The tool uses the standard email pattern: letters, numbers, and common special characters before the @, followed by a domain with a valid two-letter-or-more top-level extension, such as name@company.com or john.doe@sub.example.co.uk.
Why do I get fake addresses like name@example.com?
∨
Placeholder addresses such as user@example.com and info@domain.com are common in documentation, templates, and sample code. Turn on Ignore Placeholders and these known fake domains are automatically filtered from the results.
Why does my list contain things like logo@2x.png?
∨
Text with image paths or URLs can contain @-signs that look like emails, such as logo@2x.png or banner@1x.jpg. Enable Ignore File Names and any match ending in a common file extension (png, jpg, svg, css, and more) is filtered out.
How do I remove duplicate emails?
∨
Toggle Unique Only on. The list is deduplicated case-insensitively, so john@example.com and John@Example.com count as the same address. This is essential before importing addresses into a mailing list or CRM.
Can I use the extracted emails for marketing?
∨
The tool gives you a clean list for import into your own tools. Note that sending unsolicited email to addresses you do not own may violate anti-spam laws such as CAN-SPAM or GDPR. Always use extracted addresses in a compliant way.
Is my data sent to a server?
∨
No. All extraction, filtering, and counting happens entirely in your browser with JavaScript. Your text is never uploaded, stored, or transmitted anywhere. The page works offline after it loads.
Can I open a file instead of pasting?
∨
Yes. Click Open File and choose a .txt, .html, .htm, .csv, or .eml file from your computer. The file is read locally in your browser and its content is placed into the input panel — nothing is uploaded.
How are the emails exported?
∨
Click Save CSV to download a CSV file with one email per row, ready to open in Excel, Google Sheets, or import into a mailing service. You can also use Copy All to get a newline-separated list on your clipboard.
What file formats can I open?
∨
The Open File button accepts plain text (.txt), HTML (.html/.htm), CSV (.csv), and email message (.eml) files. Any other text-based format can be pasted directly into the input panel instead.
Are uppercase emails handled correctly?
∨
Yes. Matching is case-insensitive for duplicates, so JOHN@EXAMPLE.COM and john@example.com are treated as one address. When copied, addresses keep the form in which they first appeared in your text.
Is this tool free?
∨
Yes, completely free with no account, no registration, and no usage limits. You can extract as many emails as you like from texts of any length, and all processing happens locally in your browser.
