That means 500GB of total storage, making Proton Drive a lot more viable for people to use as a backup service. There are also additional features like a new 'short domain' email alias that you can use to send and receive messages as well as 20 calendars that you can share with other users.įinally, the Unlimited plan costs €12 / month the company is positioning it as a way to get the top tier of all its services at once.

There's no restrictions on how many messages you can send or how many labels and folders you can create, and it also supports IMAP email clients via the Proton Bridge tool. Users now get 15GB of storage shared between their email and Proton Drive cloud storage account. It's a big upgrade over the old plan, though. The Mail Plus plan will cost €5 / month, though you can get it for less if you sign up for a year or two years all in one shot. Proton has long said that since it doesn't serve ads, it relies on subscriptions for revenue, so it's not too surprising the free plan is restricted. You can also access the basic Proton VPN tool and user Proton Calendar, though you're limited to only one calendar on this plan.

The new free tier expands storage to 1GB and remains fairly constrained - you can only send 150 messages per day and have three labels and folders, for example.

Going forward, Proton will offer three plans: Free, Mail Plus and Unlimited.
