Mail Filter

Email Extraction From Raw Text, Simplified

If you work with server logs, message headers, customer lists, or any raw text dump that mixes email addresses with other content, this email filter tool does the heavy lifting for you. Paste your block of text and the tool detects and extracts every valid email address, returning a clean, unique list you can use straight away. It is a lightweight alternative to regular expression pipelines and spreadsheet formulas for everyday data cleaning and contact extraction.

Where It Helps

• Data cleaning: pull usable contact details out of legacy databases, imports, or exported reports.
• Sales and marketing: rebuild contact lists from unformatted records instead of typing them out one by one.
• IT operations: grab notification recipients or users from configuration files and support dumps.
• Research: extract emails from downloaded text files for surveys or outreach without writing a parser.

How It Works

Type or paste your source text into the text area and press Filter. The tool matches standard email patterns (local part + @ + domain) across the whole block and outputs only the addresses, ignoring surrounding punctuation and formatting. A Select All button highlights the result so you can copy it in one click, and Clear resets the input for the next batch. Everything runs in your browser — no data is uploaded to a server.

Tips for Best Results

Paste the raw text exactly as it appears, including separators and line breaks. The extractor is designed to handle noisy input, so there is no need to pre-format or deduplicate your data first. After extraction, sort and deduplicate the output in a spreadsheet if your source contained repeats.
