How to use this tool
- Paste the text that contains the addresses you need to extract.
- Choose whether exact duplicate matches should be removed.
- Run Extract addresses and review the returned list before using it.
Understanding the output
The tool finds text shaped like a conventional ASCII email address. It does not send mail, contact a server, or confirm that an address exists. Exact deduplication preserves the first occurrence and its spelling; addresses with different capitalization remain separate.
For additional case or whitespace matching rules, use Remove Duplicate Lines on the extracted list.
Two addresses with one repeat
A passage containing alex@example.com, team@example.org, and alex@example.com again produces two lines when exact deduplication is enabled. The patterns-found total remains three.
Extraction is not email verification
A string can look like an email address without accepting mail. Its domain may be inactive, the mailbox may not exist, or delivery may be restricted. This tool intentionally performs no network checks. Use the result as a candidate list for your own records and confirm important contact details through an appropriate source.
The matching rules favor ordinary addresses found in documents rather than implementing every form permitted by email standards. Quoted local parts, address literals, and internationalized mailbox names can require a dedicated parser and are outside this utility’s scope.
Review the surrounding text
A copied document may contain examples, historical contacts, or punctuation joined to an address. An extracted match should be checked against its context before it is treated as a current contact. Exact duplicates can be removed automatically, but two different strings may still refer to one mailbox through aliases or provider-specific rules. The tool does not infer those relationships.
Method and supported input
A case-insensitive pattern identifies conventional ASCII local parts and dotted domain names. Matching text is returned without surrounding prose; optional exact deduplication preserves first-seen order.
- Addresses appear directly in text rather than being written as name at domain dot com.
Limitations
- Some uncommon valid addresses will not match.
- Matches are candidates, not proof of mailbox existence, ownership, or deliverability.
Common questions
Does this check whether an address can receive email?
No. It only extracts matching text and does not contact mail servers.
Can it recognize obfuscated addresses?
No. Replace intentional obfuscation manually if it is appropriate to your task, then review the output.
