However, the latter is only able to search for email addresses and words in the subject since the message itself is encrypted – something that is not ideal if you handle a lot of emails.

Moreover, it also provides an autoresponder, contact groups, and a search bar. You can add folders and labels to arrange your inbox the way you see fit, as well as create email rules to organize them the moment they arrive in your mailbox. However, when it comes to email itself, ProtonMail has developed a user-friendly interface with the essential features you need in your daily life. In other words, it has to focus on the most important features first, and since the main objective is to secure email correspondence, it makes sense that that's what’s being tackled in priority. However, we need to take into account that this email provider is still relatively new to the game and has a somewhat limited team. Contrary to other email clients, ProtonMail does not offer some of the productive features we love, such as a built-in calendar, spell-checker, automatic translator, and task manager. There is no doubt that ProtonMail's primary concern is to provide the safest way to send (and receive) emails.

With its end-to-end encryption and zero-access architecture, communicating privately via email has never been easier. Fortunately, ProtonMail came up with a completely secure system that encrypts emails automatically, making it easy for the less tech-savvy to send messages without having to fear about eavesdropping. However, email, one of the most commonly used forms of online communication, was not built to be secure, and making sure messages are entirely private is not an easy skill to master.

After Edward Snowden leaked the NSA's global surveillance programs in 2013, internet privacy became a major concern to the average user. In 2014, ProtonMail was being used by a handful of CERN scientists nowadays, with more than 28 million users, it's one of the largest secure email providers in the world.
