Email Domain Checker

Group email addresses by common personal domains, remove duplicates and export CSV. Addresses stay in your browser. Free

Separate addresses with spaces, commas or new lines. Up to 1,000 entries. Domain rules do not verify delivery or business identity; uncommon formats are marked unsupported.

Example

alex@gmail.com → common personal domain; alex@example.com → other or unknown. Only exact domain matches are classified as personal.
