Proton Mail

Spellings of Proton Mail's official domains (protonmail.com) registered to other owners (identified by nameservers, registrar and redirects), checked daily; the ones with no address or mail server yet say so. Many are parked, for sale or run by other businesses and sites with a similar name; the ones a phishing source or address list has flagged carry a label.

Some of these come from registry zone files (ICANN CZDS). Our zone data terms apply to them: no marketing use of any kind, no harassing their registrants, no high-volume registry or registrar queries.

16 of the 139 are listed by a source or resolve to a listed address, checked hourly.

Domains from registry zone files (ICANN CZDS), checked daily like the lookalikes above. Each row says how it matches Proton Mail's names. Resellers, fans and other businesses register names like these too. Our zone data terms apply to them.
