The extractor is useful for content you already control: contact exports, support threads, HTML snippets, application logs, research notes, or documents copied as text. It finds practical mailbox syntax without opening links, sending messages, or checking any mail server. Treat the output as a list of candidates, because a correctly shaped address can still be misspelled, inactive, or undeliverable.
Use extracted addresses responsibly. Finding an address does not give permission to send unsolicited messages. Follow the consent, privacy, and anti-spam rules that apply to your location and intended use.
