What's very indicative of ProtonMail's high-security system is where their servers are located. The truth is ProtonMail's servers are locked down underneath a kilometer of soil within a Swiss bunker that can withstand a nuclear attack.

What began as a simple principle where no other person apart from the one you send the email to can read the contents. The email service provider has made that mission into their overall statement. 

It even came to a point that email servers and the staff that work within the company cannot read or share your emails. ProtonMail is based in Switzerland and is protected by the country's data security protocol. 

The service provider offers one of the best privacy protections across the entire world. Even if your email was captured, though almost impossible to do so, no one would still be able to decipher it.



The emails are already encrypted long before they are sent to the servers. This ultimately means that not even hackers can decrypt or read the emails that you sent. 

Fortunately, the service is offered at a rate of around $5 - $30 a month and is available through iOS, Android, and browser.

With its server located in Germany, one can determine that is truly made for business users. The email service is dedicated to bringing more security measures to your business transactions.

Tutanota uses DNS-based Authentication of Named Entities or DANE to secure their service from hackers. This works especially against hackers who try to impersonate you or your recipients and set you up for identity theft or worse.

The recipient will receive a single-use version of Tutanota so they can reply to the email with all the encryption services in full effect.


The email service is currently free for up to 1GB of storage. However, if you want to unlock features such as filters and custom domains, the service is priced at around 1 euro per month. Tutanota is available for webmail alongside Android and iOS devices.
