Email Domain Counter

Group structurally valid email addresses by normalized domain and rank domain counts locally.

Email list

ReadyOutput is ranked by count, then domain name.

These tools work locally on text. Syntax validation is not mailbox verification: no DNS/MX lookup, SMTP connection, account-existence check, or deliverability test is performed.

Counts that lead directly to export

Rank normalized domains by frequency and expose copy/download actions without routing the contact list through a server.

Deliverability remains a separate network question

These tools intentionally stop at local parsing, normalization and URI construction. A syntactically valid address can still have no MX service, no mailbox, a catch-all domain, or delivery restrictions; v266 does not label those network states without actually checking them.
