7 Secure Email Service Platforms in 2023

best secure email service platforms

Have you ever thought why many businesses don’t use mail services like Gmail, and Yahoo mail which are available for free? It’s because these email services are not secure enough to handle sensitive information. Businesses that have tons of sensitive information to share need secure email service platforms.

Secure email platforms basically have a higher level of encryption compared to Gmail, Yahoo Mail, etc.

Moreover, ordinary email platforms also collect data to show you personalized ads that can be annoying. As a business, you should aim to secure sensitive information. One of the best ways to do so is by using a secure email platform.

In this guide, we’ll be going over the list of the most secure email providers.

Why Does Your Business Need Secure Email?

Google, Microsoft, and Yahoo are very popular email service providers but they’re not secure. To protect sensitive information from outside threats, businesses need secure email solutions. 

However that’s not the only reason, here are some more reasons you should consider getting a secure email service:

  1. Additional Layer of Encryption: A secure email service protects your messages with end-to-end encryption services. It prevents you from hackers and malicious threats as well.
  1. Enhanced Privacy: The metadata of the email contains the sender’s, and receiver’s email addresses as well as the date and time of the mail. Secure email services hide your metadata and maintain the sender’s and receiver’s privacy.
  1. Two-Factor Authentication: Almost all secure email service providers offer two-factor authentication to prevent account takeover. Some services even include a VPN service to enhance the overall level of security.

7 Best Email Service Providers to Try Out

Just a quick Google search of “secure email providers” will give you over 3 dozen results. How will you know which one is best for you?
