Email Encryption Buyer’s Guide

Deciding which email encryption platform to use isn’t as simple as picking the first one you see. Instead, you need to consider many key factors to find the right option.

In this buyer’s guide, you’ll find the most important factors, so be sure to take the points we make on board.

Security Features

Probably the most important factor affecting your decision is security features. The platform you choose must have the necessary security features to protect your emails. If your chosen platform doesn’t have the features you need, your emails could be attacked quickly.

Your service should offer protection from viruses, hackers, eavesdropping, phishing, and spyware.

Ease of Use

The platform you decide to use will be responsible for protecting sensitive information and client details. Therefore, you need to be able to use it correctly and easily.

With this in mind, it is important to find an email encryption platform that is intuitive, straightforward, and requires little effort to get right.

Aside from a simple yet effective website, you can find a platform that is easy to use by reading reviews and identifying key factors that make the whole process easier.

For example, a platform that offers automation is much easier to use than one that doesn’t.


For the email encryption service to work with your business’s emails, you must ensure it’s compatible. Whilst most platforms are compatible across most devices, and operating systems, not all of them cover everything.

Some might only specialize in more popular systems like Gmail. As a result, you should consider the email account you’ll be using and then look at the platforms that offer the best service for that account.

Doing this will ensure you don’t instantly feel regret when you start using the wrong platform.


Of course, you’ll also have to consider pricing at some point. This is important for many reasons. Firstly, you don’t want to pay a subscription fee that you can’t afford to keep up the costs. Secondly, you can save money by avoiding expensive platforms that offer services you don’t need.

Finally, you can save time by only looking at the platforms that fit your budget.

With all of this in mind, we recommend setting yourself a budget. Only then should you start seriously considering the services you need.

By doing this, you can save time by only looking at the platforms you can afford, avoid overspending, and, most importantly, evaluate the features you need.

This can help you avoid the purchase of any unnecessary features.
