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, and internationalized domain names. Results are auto-deduplicated and format-validated, exportable as comma or line-separated lists.
