Top 5 Secure Email Service You Should Use

secure email

Electronic Mail or “Email” was one of the first modes of digital communication. In today’s digital and tech-savvy world, it has become an important necessity to have an email address. It is almost similar to having a driving license. With the increase in the popularity of emails, the risks of cyber-attacks involving email also increased rapidly. Thus, the need for Secure Mail Services like Proton mail, Kolab now, Mailfence, and Tutanota increased.

A major behind this is that people don’t pay attention to some key aspects such as privacy while creating an email account and the email service providers take advantage of this fact by selling their usage statistics and data to other companies to gain huge profits.

Thus, while creating an email account, it is very important to read and understand the platform’s privacy policy and security measures. Most people today have a Gmail account because it is a very popular and most used service. Most of the user data is sold by Google so it is highly insecure. So, we have created a list of the top 5 most secure email service providers which are way more secure and privacy-friendly than Gmail or some other popular mail service –

It follows the principle of zero access and zero-knowledge, which means that the servers and working staff have no way of accessing or sharing your emails. ProtonMail also provides excellent mobile app services.
