How to choose the right email service

1

Make a list of your needs

Start by listing all the features from an email service that you can’t live without. The main tradeoff that you’re going to have to do is between security and email management features. This way, it’s essential for you to pinpoint if straightforward end-to-end encryption is more (or less) important than features like built-in calendar, email rules, and so on.

After knowing what you really need to have, it’s essential to understand where you are going to access your email from. For example, some email services are perfect on the desktop but don’t offer a mobile application. It’s also vital to understand your daily email usage since email services’ plans differ on the amount of email storage provided.

2

Research

Now that you have a clear idea of what you want, it’s time to do some research. It’s essential to read top rankings, reviews, and comparisons to narrow the options down to one. Although on the surface some email services may seem equal, after reading about them, you’ll notice that one is always going to come up on top. It might be a specific feature or the company’s mission statement, but we guarantee that one will be the winner.

Get the best deal

When you have pinpointed what email service you are going to use, it’s time to look for discounts and free ways to test the product. There are always methods to save money, and our coupons and free trial pages will tell you how.

Secure email usage

Using a secure email service is just the first step to guarantee your privacy online. There are many ways that hackers can exploit your devices, and email providers can only do so much.

First, you must use strong and secure passwords and change them regularly. Using a password manager is the best way to create and store multiple passwords, mainly because they generate military-grade passwords for you. Of course, you should always use multi-step authentication whenever possible as well.

New phishing attempts happen every single day, and it’s impossible for email providers to have a complete list of all the phishing accounts. So, you must be aware of the emails you receive and double-check if they’re trustworthy before clicking on any link or sending personal information. Antiviruses are a great help since they scan emails to find phishing attempts as well as malware. Better yet, the protection they provide is not confined to email, protecting your device from all different kinds of cyber attacks.

Finally, you need to think about the connection between your computer and the email service’s servers. Secure email providers will indeed use the safest connections on their websites, but there are things that they can’t influence. Using a VPN is always advisable, especially when using a public Wi-Fi to establish an internet connection.

Secure email usage

Free secure email services

It’s common practice in the email service industry to have free plans, and secure email providers are no different. Most of the time, there are forever-free packages that you can use and, although limited, most of them will suffice for personal use. However, like the paid subscriptions, free plans change tremendously depending on the email service’s pricing strategy.

Private-Mail, for example, heavily limits its service’s features for free users, basically offering only encrypted email. On the other hand, ProtonMail provides most of its features but limits the number of daily messages to 150. As a third option, eM Client gives away its full service for free but limits you to personal use of only two email accounts.

However, there is something that you’ll always get with a secure email service on its free option, and that is privacy and protection. So, if you are a light email user who wants to use a safe email provider for personal use, a free plan will suffice.
