About Email Extractor
This email extractor uses a precise regex based on RFC 5322 to identify and extract all valid email addresses from arbitrary text. Matching covers local-part@domain structure, supporting plus-aliases, subdomains, dot separators, and internationalized domain names (IDN). Results are auto-deduplicated and format-validated, exportable as comma- or line-separated lists. For example, pulling email addresses like name@example.com out of a comment block and deduping them builds a contact list fast. Regex matching in the browser is near-instant, but keep expectations realistic: an intentionally obfuscated string like "name at example dot com" is not a valid email and will not match, since the tool extracts well-formed addresses rather than guessing at disguised ones. Everything runs locally with no network requests, so customer lists, mail logs, or CRM exports stay on your device. Last, use results legally - unsolicited bulk mail may violate anti-spam laws, so obtain consent and provide an unsubscribe path for commercial campaigns.

FAQ
Can it extract Gmail plus-alias emails?
Yes. The tool supports user+tag@gmail.com format plus-alias emails and also handles subdomains and dot separators.
Are extracted emails deduplicated?
Yes. Each email appears only once even if duplicated, and addresses failing RFC 5322 format validation are auto-filtered.
Does it support internationalized email domains?
Yes. The tool recognizes internationalized domain name (IDN) format emails with Unicode characters in the domain part.
Can it retrieve obfuscated emails?
No. Strings rewritten like "name at example dot com" are not valid email addresses and will not match; restore them to real addresses first.
Can I customize the export format?
Yes. Results can be exported as comma-separated (for spreadsheet import) or line-separated (for text lists).
Can I bulk-send to the extracted emails?
Unsolicited bulk sending may violate anti-spam laws such as GDPR or CAN-SPAM. Get consent and provide an unsubscribe option for commercial campaigns.
Is my data uploaded?
No. Extraction runs locally in the browser via the regex engine with no network requests, safe for customer-contacting text.
