“Your calendar is far more than a list of appointments. Paid accounts have no limits.Andy Yen, Founder and CEO of Proton, said: Interestingly, free accounts are also limited to only 150 messages per day. A 5GB account can be had for between 3 and 5 Euros per month, depending on subscription length (longer is cheaper).

Of course you can choose to use the premium service and upgrade your inbox size, but for now we are sticking to the free version. If you compare that to other offerings, you would typically expect inboxes to have multiple gigabytes of storage space. Unfortunately, free accounts don't get a lot of storage space.

In addition to encryption, the service also offers advanced security options such as two-factor authentication that can help keep hackers out of your account. That's because your password isn't merely for logging into the service, but it is also an encryption key that unlocks your account. This means that absolutely no one, not even ProtonMail themselves, can access your account without your password. The biggest advantage offered by ProtonMail is that all accounts are encrypted. ProtonMail is an encrypted email service whose creators have a 'shared vision of protecting civil liberties online' through technology.

Still, it can be a little unnerving to know that an algorithm is poking and prodding through your love notes, fights with your boss, and doctor's appointment confirmations. This hasn't stopped millions of users from joining the service, however. It's a well-known fact that email providers like Gmail will search through your emails to find ways to target you with advertisements.
