Features to look for in a secure email service
The fact that an email service is secure does not mean it is safe and can provide optimum privacy. Many secure email services in the market today have caused danger and contributed to data breaches. Hence, it’s essential that the email service you select has these features:
- Two-factor authentication (2FA): This feature provides extra security and protects your account and data if someone cracks your password. Including another device or system in your account makes it harder for a hacker or unauthorized third party to open and access your email. Common 2FA options include SMS and Google’s authenticator apps.
- End-to-end encryption: This feature is vital in ensuring security and privacy. You shouldn’t pick any email service without end-to-end encryption. The regular encryption technology only encrypts your email until it reaches the email service provider’s end. However, end-to-end encryption permits only the sender and receiver to open the message. PGP encryption is the most common end-to-end encryption for secure email providers.
- Server location: You must also consider the region where the email service’s server is located. This is essential because not all countries have privacy-friendly laws. Some countries have data retention laws mandating service providers to store users’ personal data for a period. Avoid email service providers with servers in the United States, the United Kingdom, Australia, and Canada, as they share signals intelligence data as members of the Five Eyes intelligence network.
- Stripping metadata headers: Typically, emails bear metadata about users, including their device, web browser, and sometimes the recipient. Secure email service providers leave out this information to promote users’ privacy and security.
How does secure email work?
End-to-end encryption is the feature that distinguishes a secure email service from a regular email service. This technology ensures that emails remain exclusive to the sender and recipient. No third party, even the email service provider, can decrypt the email. Regular email service providers, like Google, can read your emails. Emails you send using a regular service provider are susceptible to hacker interception.
Most secure email service providers either use S/MIME or PGP for email encryption. While S/MIME uses certificates that a local or public certificate authority must sign, PGP utilizes asymmetric and symmetric encryption. S/MIME strategy guarantees the authenticity of an email, as the certificate proves that you’re the sender of the mail and that nobody has intercepted the delivery.
Encryption services make it impossible for prying eyes, hackers, ISPs, or the government to view your message or details.
End-to-end encryption
End-to-end encryption guarantees the exclusivity of emails, concealing your messages from your third parties. Email service providers with end-to-end encryption cannot decrypt their users’ messages. Only the sender and recipient have private and public keys to access the message.
When you email your colleague, you encrypt the message with your colleague’s public key. This encrypted message passes through different servers until it gets to the destination. Only your colleague’s private key can decrypt the message. Hence, it cannot be intercepted as it passes through the different servers.
Transport-level encryption
Transport-level encryption ensures that users’ messages travel across the web safely. This is not enough to guarantee the safe and secure delivery of emails, as email providers can access the unencrypted version when it gets to their server. It utilizes either TLS (Transport Layer Security) or SSL (Secure Sockets Layer), although SSL precedes TLS, and combines with TCP (Transmission Control Protocol) to encrypt emails (SMTP and IMAP) and other protocols like FTP and HTTP.
Virtually all mail services don’t use this system. It may be difficult for a regular user to figure it out because email services don’t notify users when using transport-level encryption, unlike a web browser that displays a green lock or related icon.
PGP email encryption
Unlike end-to-end encryption, PGP email encryption guarantees email exclusivity without exchanging private keys. It combines symmetric encryption, hashing, and public-key encryption. Email services that adopt this encryption system perform the encryption without bothering users.
The recipient’s public key encrypts the session key PGP generates. Then the sender delivers the encrypted session key for the recipient to decrypt with the private key. The recipient then opens the message using the unencrypted session key.
Conclusion
Whether or not you’re privacy-conscious, using a secure email service provider can boost your immunity against hackers and cybercrimes. Business professionals also need a secure communication channel so sensitive information doesn’t get into the wrong hands.

An encrypted email is indecipherable and unreadable, preventing unauthorized individuals from reading the original message. Typically, messages are sent and received in plain and readable form, so anybody can intercept and read them. However, secure email service providers encrypt the messages so only authorized recipients can read the original text, while others can only see the scrambled version.
Gmail utilizes Transport Layer Security (TLS) encryption to secure emails. TLS encrypts your message if the recipient’s email service provider also utilizes TLS. However, once the email gets to the mailbox, the service provider can view the content of the message.
While it’s easier to discover the activities of a hacker on your email account, determining if someone else reads your private emails is challenging. What you can do is prevent this from happening by using end-to-end encryption.
