Email is a must-have service required to fulfill your daily business and personal needs these days. It is considered one of the most professional ways to communicate with your clients or other businesses. Few people use third-party email service providers such as Gmail for free and personal use, but it is not an official email for business. You have to create emails ending with your business domain name that you need to register a domain name and hosting package to set up your business website and number of professional emails. In this guide, I will share prominent features of the top 10 secure email providers to choose one of them as per your requirements.

On average, people spend more than 5 hours per day checking personal, promotional, business, or work emails. Hackers mostly attack your personal or business email to collect useful information to access your company’s data. Most of the users use Gmail or outlook for free, which is a less secure option, so you have to protect your valuable information sent daily via a secure email provider. So let’s start with a basic introduction to secure email providers.

What are Secure Email Providers?

As the name indicates, a secure email provider is specially designed to keep the email account and information of your emails secure. Hackers also try to hack your email’s data when sent between two nodes. To secure the data when sent from one point to another, end-to-end encryption is used, which means email is fully encrypted from sender to recipient.

Like all web hosting providers claim that they all provide 100% uptime, every email provider is calling itself secure. It is the basic reason I am sharing the main points of the top 10 secure email providers so that you can read them and choose one of the best suited. You can check their encryption protocols and other security practices they are using.

Why Do We Need Secure Email Providers?

Suppose you send an email containing your data using a standard email provider such as Gmail. However, those standard email providers also deliver security, but they use the Transport Layer Security (TLS) encryption method to secure your emails in transit between you and the server.

When your email is safely transferred to the server, Google encrypts the data at a network level and sends it to the concerned recipient. Google itself has access to your data that can be risky for a few people. It is stated they no longer read your emails for ads, as they did before the year 2017. But still, Google scans your email’s content to deliver you additional features such as Smart Reply. They can also provide access to other third parties to access your emails.

So, let me complete the complete cycle; your email is now traveling to the destination and leaving Google’s server. If the receiver uses the same transport layer security, it will continue to be protected. If your recipient is not using the same TLS security, your email will be unencrypted and intercepted easily. In another scenario, your email may not be the same when it reaches the recipient’s email server because some email providers don’t encrypt emails on servers.

How to Choose Secure Email Provider?

Many factors are considered to check which email provider fulfills the specific requirements.

Encryption Method

There are different methods used for end-to-end encryption and decryption. Mainly there are two types of encryptions which are symmetric and asymmetric.

Symmetric encryption uses two different and unique sets of keys to encrypt the data, and it is also known as public-key encryption. In this scenario, the user will send an email using the public key of the recipients. He will receive the email and decrypt the email using a private key mathematically linked to his public key.

Asymmetric encryption is not simple compared to symmetric because it adds an extra layer of security to keep the emails more secure. So, you have to check which email provider is offering asymmetric or symmetric encryption, and you can choose one of them per your required level of security and encryption.

Two-Factor Authentication

Two-Factor Authentication

It is extra protection to make sure that account credentials are fully protected. 2FA means that if someone hacks and steals your credentials, it won’t be enough to get into the email account. He will also need to steal your phone to log into email. When you try to log in to your email account, an authentication code will be sent on the mobile to verify that it’s you.

Open-Source Code

It means, if an email provider is open-source, then their source code will be available publicly, and anyone can examine it and ensure that it is secure.

Metadata Header Stripping

Email header contains all the information related to the recipient, browser, network, and sender’s computer. Many secure email providers know the importance of this meta information, and they strip this info out.

Mobile and Desktop Usability

Although you need a secure and encrypted email, you will also need a better user experience. So, a great email provider can never ignore both mobile and desktop usability.
