In users’ own words
“When going from family subscription to proton wallet, there is an option to "upgrade" which I don't believe is anywhere else on the website. Even from the proton mail dashboard in select plan section this extra 6TB subscription is nowhere near. Is there a reason why it's hidden? Honestly I would go for that 6TB option if it was presented to me with full details and maybe slightly higher limits? I can't really tell…”
“The Karnataka High Court has directed the Union Government to initiate legal proceedings to block Proton Mail in India under provisions of the Information Technology (IT) Act, 2000. Justice M Nagaprasanna issued the direction on Monday, April 28 while allowing a petition filed by M Moser Design Associates India Private Limited, a Bengaluru-based firm. Proton Mail is a Switzerland-based encrypted email service that…”
“I wanted to migrate my 15 year archive of email into ProtonMail, so that I would have access to old messages on my phone, but get it out of Gmail. Problem is that it has caused Proton Mail to slow down (~1 minute to open the app now). I'm assuming this has something to do with decrypting the metadata on ~140K messages. Is there something I can do to only have to decrypt the metadata on my old emails when I go…”

About Proton Mail
FreemiumBeginner-friendlyNo APIWeb · Mobile · Desktop
Proton Mail is an end-to-end encrypted email service based in Switzerland, founded in 2014 by CERN scientists. It protects your communications with zero-access encryption, meaning neither Proton nor anyone else can read your data. The free tier includes 1 GB storage and one encrypted email address, while paid plans add custom domains, VPN, Drive, Pass, and more. Over 100 million users rely on Proton Mail for privacy. It's ideal for journalists, activists, and anyone escaping Big Tech surveillance. Compared to Tutanota, Proton offers a broader ecosystem (VPN, Drive, Pass, AI) and stronger brand trust, but its free storage is smaller.
Behind the Verdict
Proton Mail is the go-to for secure email when you need a full privacy ecosystem. Pick it if you value zero-access encryption and Swiss law protection. Skip it if you need generous free storage or deep collaboration features (limited calendar sharing). Compared to Tutanota, Proton's extras like VPN and Password Manager make it a better value for bundle seekers. Real-world caveat: IMAP/SMTP requires the Bridge app (paid), so desktop clients aren't trivial. Also, Proton Messages to non-Proton users are password-protected links, not true end-to-end—manage expectations.
