Find patterns rather than verify existence

Email matching targets common ASCII address syntax and does not support internationalized local parts. Domains are lowercased while URL paths and queries are omitted. Text such as a filename can match a domain-like pattern.

Bounded list cleanup

Source text is bounded to 100,000 characters and results to 5,000 entries. Email case is preserved and exact duplicates are removed. No contact list is retained and deliverability is not queried.

Common questions

Are messages sent to extracted addresses?

Only the resulting text is displayed, copied or saved when you choose. No mail is sent and no request is made to an extracted domain.
