1,608 of the 1,000,000 top sites in our Tranco top-1M census run Proton Mail (0.2%). An encrypted email service focused on privacy, often used for a domain's inbound and outbound mail. Detection is homepage-level HTML/header fingerprinting, so a site can run Proton Mail on other pages without it showing here.
