The problem with protecting your email is that it must be encrypted end-to-end to prevent it from being intercepted while traveling on intermediary networks, and the recipient also needs to have the same encryption system. Although some of these systems are free, they are difficult to configure in general and try to convince the other user of the importance of carrying out the process, it can be useless. The way in which email protocols work also facilitates data leaks, because the mail remains in a service, waiting to be collected. However, if you still need to use email to send confidential data, or just want to keep your emails private, there are a few secure email services that you can rely on. Each email provider offers the high level of security and great features that can benefit you over other standard email services.
Here are our top 10 secure email providers that you can use for messaging and communicating:

Using any secure email providers from the above list is up to you, but you can make your email even securer by using a VPN service. VPN creates a secure connection between your computer and the network (the email service provider). When you enable the VPN service, the internet traffic (emails, messaging, etc.,) travels through the VPN connection first. This means VPN secures your email, web browsing, chat, etc., from scammers and hackers.
So, if you have a VPN, enable it and keep yourself secure.
