The Email Extractor scans input text or documents using high-accuracy RFC 5322 regular expression pattern matching to find all valid email addresses. It cleans trailing punctuation and allows deduplication, domain whitelisting/blacklisting, TLD filtering, role account classification, obfuscated address parsing, and multi-format exporting.

Yes! You can enter a domain whitelist filter (e.g. 'gmail.com' or 'telekit'), domain blacklist filter, or click a quick domain filter pill. You can also toggle 'Exclude Disposable / Fake' to automatically strip temporary and sandbox domains like example.com, mailinator.com, or test.com.

The parser automatically resolves anti-spam obfuscation patterns such as 'user [at] domain [dot] com', 'user (at) domain (dot) com', 'user AT domain DOT com', 'user at domain dot com', and HTML character entities like '@' and '.' into standard usable email addresses.

You can copy or export results in 10 different formats: line-separated text (.txt), comma-separated list, semicolon-separated list, space-separated, tab-separated, JSON Array, JSON Key-Value Map, CSV table with metadata columns (Email, Username, Domain, TLD, Category, IsRole, IsDisposable), SQL INSERT statements, and Markdown summary tables.

No. All extraction, filtering, sorting, and reporting logic runs 100% locally inside your web browser JavaScript engine. Your email lists and sensitive text remain completely private with zero network uploads and zero server logging.

Yes. You can drag and drop any .txt, .html, .log, .csv, .json, .md, or .eml file directly onto the input workspace or click 'Upload File' to parse files up to dozens of megabytes in size.

Our parser automatically classifies addresses matching common administrative, corporate, and operational prefixes (such as support@, sales@, info@, billing@, admin@, press@, jobs@, and abuse@). Using the 'Account Type / Role' dropdown, you can isolate strictly role mailboxes (🏢 Role Only) or exclude them (👤 Personal Only) to keep your direct outreach lists clean and improve deliverability.

Yes. In the export suite at the bottom of the workspace, you can customize the base filename (default: 'extracted_emails') and toggle '+Date' to automatically append today's ISO date stamp (e.g. 'extracted_emails_20261020.csv'). The interactive live filename preview badge (📄 Target: <filename>) allows you to copy the resolved filename with a single click, and our 1-Click Quick Copy Action Strip offers instant exports across 6 formats (Alt+1..6).

Click the '💻 API Code' button in the hero toolbar or press Alt+S to open the Developer API & Integration Code Studio modal. We provide production-tested regex extraction code snippets across 6 languages (JavaScript/Node.js, Python 3, PHP 8+, Go, Rust, and Bash/ripgrep) with 1-click standalone script file downloads.

Use 'Alt+P' for DevToys Smart Clipboard Auto-Detect, 'Alt+D' to bookmark the tool, 'Alt+T' (or '/') to focus the raw editor, 'Alt+U' to upload files, 'Alt+V' to switch between 2-Column Split Studio and Stacked density, 'Alt+S' for the Developer API Code Studio, 'Alt+R' for benchmark test scenarios, 'Alt+1' through 'Alt+6' for 1-Click Quick Copy formats (Newline, Comma, JSON Array, Markdown Table, CSV Matrix, JSON Audit Report), 'Ctrl+Enter' to copy output, and 'Escape' to dismiss open modals or clear search.
