Email Extractor Online

Free Email Extractor Online

An online email extractor pulls email addresses out of larger blocks of content so you do not have to find them one by one. Paste a document, a copied contact list, an email thread, a log file, or HTML source code, and the tool returns the addresses it finds, ready to review, clean, and export.

This tool extracts multiple addresses at once, detects duplicates, groups addresses by domain, and prepares clean lists for download as TXT, CSV, or JSON. It works only on content you provide by pasting text or loading a file. It does not browse websites or look anything up on its own. If you want a simpler, address-only workflow, our Email Address Extractor is also available.

What Is an Email Extractor?

An email extractor scans text for patterns that look like email addresses: a local part, an @ sign, and a domain such as example.com. Pattern matching lets it find addresses inside sentences, tables, signatures, source code, and exported data, regardless of the surrounding text.

Extracting from mixed content is faster and more consistent than searching manually, especially when the same addresses appear many times or are mixed with names, phone numbers, and links. It also reduces copy-and-paste mistakes.

Extraction is not verification. An extractor tells you which strings look like email addresses. It cannot tell you whether the mailbox exists or whether the address belongs to an active person or organization.

• Search and domain filtering with include and exclude modes, plus sorting by order, name, domain, or count.
• Selection and manual cleanup: select, copy, or delete individual results, with undo and restore.
• Domain summaries with unique addresses, occurrences, and percentages.
• Basic syntax checks that flag addresses needing review.
• Copy and download for lists, TXT, CSV, JSON, and the domain summary.

How to Use the Email Extractor

1. Paste text into the input box or load a supported file.
2. Click Extract Email Addresses.
3. Review the number of occurrences and unique addresses found.
4. Keep or remove duplicates, or turn lowercase normalization on or off.
5. Search, sort, and filter the results by domain.
6. Select individual addresses or copy everything that is relevant.
7. Pick an output format such as one per line, comma-separated, CSV, or JSON.
8. Download the cleaned list if you need a file.

Your source text stays in the input box, so you can edit it and extract again at any time. Deleting results never changes the source text.

Where Can You Extract Email Addresses From?

Plain text and copied content

Text copied from webpages, documents, chats, and notes works well. If the page shows an address as an image or builds it with a script, it will not be in the copied text, so it cannot be extracted.

Email messages and signatures

Paste a thread or save a message as an EML file and load it. Headers and signatures often contain addresses, so you may see both senders and recipients.

HTML source code

Copy the page source and paste it in, or load an HTML file. The HTML is treated as plain text and is never run. Addresses inside mailto: links are found, while addresses written with scripts or encoding tricks may not be.

CSV and spreadsheet exports

Export your spreadsheet as CSV or TSV and load it. The tool reads text, not Excel workbooks, so save spreadsheets in a text format first.

JSON and XML data

Addresses stored as values in JSON and XML are found like any other text. Escaped or encoded values may need to be decoded first.

Logs and technical documents

Log files and error reports can contain many repeated addresses. Duplicate removal and domain summaries help make them readable. Technical strings such as image names may resemble addresses, so review the results.

Contact lists

Lists with names, companies, and addresses on the same line work well. Only the address is extracted, not the surrounding names.

Markdown and other text-based files

Markdown notes and other plain text files load directly. PDF and Word files are not supported. Scanned documents and images contain pictures of text, not selectable text, so a text extractor cannot read them.

How to Remove Duplicate Email Addresses

The same address often appears many times in copied threads, signatures, contact lists, and exported datasets. Listing it once gives you a shorter, cleaner list and a more accurate count.

This tool compares addresses without regard to letter case, so [email protected] and [email protected] count as one address. The first occurrence is kept, along with its original spelling and its position in the list. The occurrence count shows how many times it appeared.

Lowercase normalization is a separate, optional setting. Turn it on if you want every address shown in lowercase. You can leave duplicates in by turning off the duplicate setting, and turn it back on to collapse them again.

Understanding Email Domains

The domain is the part of an address after the @ sign. In [email protected], the domain is example.com. The part before the @ is the local part.

Filtering by domain helps you organize a contact list by organization, separate work addresses from personal ones, or leave out domains you do not need. The domain analysis shows how many unique addresses each domain has and what share of the list it represents.

A domain summary only describes the text you provided. It does not show that a domain exists or can receive messages.

Email Extraction vs Email Verification

This tool extracts addresses and applies basic syntax checks. It does not verify mailboxes and cannot guarantee that a message will be delivered.

Supported Input and Output Formats

Input: you can paste text or load TXT, CSV, TSV, HTML, HTM, JSON, XML, LOG, MD, and EML files up to 5 MB. Files are read as text in your browser. PDF, Word, Excel workbook, and image files are not supported.

Output: a list is available as one address per line, or separated by commas, semicolons, or spaces. TXT downloads contain a plain list. CSV downloads contain a header row and only the columns you select. JSON downloads contain a total and an array of objects with the fields you select.

One address per line is convenient for pasting into other tools. CSV suits spreadsheets and imports that need columns such as the domain or the count. JSON suits scripts and applications. Once you have addresses you are allowed to contact, you can use our HTML Email Builder to design a message or our Email Template Builder to create reusable text templates.

Common Email Extraction Problems

• Surrounding punctuation. Quotes, brackets, commas, and full stops next to an address are left out of the result.
• Different casing. The same address in different cases is treated as one address.
• Obfuscated addresses. Patterns such as name [at] example [dot] com are found only when the obfuscation option is on. Unusual wording is still missed.
• Invalid or incomplete syntax. Strings such as double dots or a missing domain ending may be extracted but marked as needing review, or skipped.
• Addresses in code. They are found when written as plain text. Addresses built by scripts or encoded are not.
• Scanned images and PDFs. Pictures of text contain no selectable text, so nothing can be extracted.
• False positives. Items such as image file names that resemble addresses can appear. The tool skips common image and web-asset endings, but unusual formatting can still produce a match, so review the list.

Responsible Use of Extracted Email Addresses

Finding an email address does not give you permission to contact its owner. Respect privacy, applicable laws, consent requirements, and anti-spam rules when collecting, storing, or using contact information. Rules differ between countries and situations, so check what applies to you.

Use extracted addresses only for purposes the owners would reasonably expect, and remove anyone who asks. When you write to people you have a legitimate reason to contact, our Email Templates can help with the wording, including copy-ready options for Microsoft Outlook and Gmail.

Privacy and Browser-Based Processing

Parsing, duplicate removal, filtering, organizing, copying, and downloading all run in your browser. Uploaded files are read locally with the browser's file features and are not transmitted to a server by this tool. The tool does not call outside services and does not save your text or results; they stay in the page until you close or reload it.

Browser-based processing does not make your device secure by itself. Content you copy or download can still be stored in your clipboard, downloads folder, or browser extensions, so handle exported lists carefully.
