Are you worried about your emails getting into the wrong hands? With email breaches on the rise - it's a valid concern.
In fact, around 94% of malware is delivered via email - making encryption more important than ever.
Encrypting your emails adds a layer of security that keeps your messages private and safe from hackers.
Whether you use Gmail, Outlook, or another service - email encryption is easier than you might think.
In this guide, we’ll show you how to encrypt emails on various platforms - helping you protect your information and communicate securely.
What is Email Encryption?

Email encryption is a method used to protect your emails from being read by anyone other than the intended recipient. It works by converting your message into scrambled code that only the recipient can decode and read using a special key. This helps keep sensitive information like personal details, financial data, or business secrets safe from hackers or unauthorized access.
Without encryption, your emails can be intercepted and easily read by others. Whether for personal use or business, email encryption adds a vital layer of security - guaranteeing that your private messages stay private and secure from cyber threats.
Example of Email Encryption
Let’s say you’re emailing your bank account details to a friend to split a bill.
- Without encryption - anyone intercepting the email can see those details.
- With email encryption - the message is scrambled into code that only your friend can unlock and read.
This keeps your account information safe from hackers.
How Does Email Encryption Work?

Email encryption works by converting your email content into a jumbled format that only the intended recipient can read. Here’s a simple breakdown of how it works:
1. Encryption Process:
- Senders: When you send an encrypted email - your email client uses an encryption algorithm to convert the email into a coded format. This involves using a unique key or password.
- Recipients: The recipient receives the scrambled email and uses their own decryption key or password to decode it back into readable format.
2. Keys:
- Public Key: Used to encrypt the email. It is shared with others.
- Private Key: Used to decrypt the email. It is kept secret by the recipient.
3. Secure Communication:
The encrypted email is safe from unauthorized access. Even if intercepted, the content remains unreadable without the decryption key.
By following these steps, email encryption guarantees that only the intended recipient can access and read your messages.
Benefits of Email Encryption

Did you know? Nearly 1.2% of all emails sent are harmful or unsafe.
And a report by security company Egress found that - 94% of organizations were targeted by phishing attacks in 2023.
That’s why it is important to encrypt your emails.
Email encryption is like putting your message in a secure, locked box that only the intended person can open. Here are the main benefits:
1. Helps to Maintain Privacy
Email encryption guarantees that only the intended recipient can read your message. Data shows that - more than 75% of cyberattacks begin with an email. Encryption helps protect sensitive information from unauthorized access - maintaining the confidentiality of your communications.
2. Improves Security
Encryption guards against cyber-attacks. Did you know? Cybercriminals send around 3.4 billion phishing emails every day - making it the most common type of cybercrime. By encrypting your emails - you significantly reduce the risk of hackers accessing your personal or business information while it’s being transmitted.
3. Increases Trust
Using encryption shows recipients that you prioritize their security. This can strengthen professional relationships and improve your reputation for safeguarding data. That’s why the global email encryption market is expected to grow from $6.2 billion in 2023 to $16.3 billion by 2028 - with an annual growth rate of 21.3%.
4. Regulatory Compliance
Many industries are required to protect data under laws like GDPR and HIPAA. For example, GDPR fines can reach up to €20 million or 4% of annual global turnover. Encryption helps guarantee you comply with these regulations, avoiding costly penalties and legal issues.
Types of Email Encryption

Using the right encryption method can protect your information from online threats and unauthorized access. Here are the main types of email encryption:
1. SSL/TLS/STARTTLS Encryption
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols used to create a secure connection between email servers. When you send an email - SSL/TLS guarantees that the email data is encrypted as it travels from your server to the recipient’s server. This prevents eavesdroppers from reading or tampering with the email while it is in transit.
STARTTLS is a command used to upgrade an existing insecure connection to a secure one using TLS - if both email servers support it. These methods protect emails during their journey across the internet but do not secure emails once they reach the recipient's server.
2. PGP/MIME Encryption
PGP (Pretty Good Privacy) is a method that uses encryption keys to protect email content. Each user has a pair of keys - a public key, which is shared with others to encrypt messages sent to them, and a private key, which is kept secret and used to decrypt incoming messages.
PGP/MIME is an extension of PGP that allows encryption of emails that include attachments or multiple parts - guaranteeing that all parts of the email - including attachments, remain secure. This method provides both encryption and digital signing to verify the sender’s identity and protect the email’s content.
3. S/MIME Encryption
S/MIME (Secure/Multipurpose Internet Mail Extensions) uses digital certificates to encrypt and sign emails. A digital certificate is an electronic document that verifies the sender’s identity and contains a public key for encrypting messages and a private key for decrypting them.
When an email is sent using S/MIME - it is encrypted with the recipient’s public key - and only the recipient’s private key can decrypt it. S/MIME also adds a digital signature to the email, which allows recipients to verify the sender’s identity and guarantee the email has not been altered. This method is commonly used in corporate settings for secure and verified email communication.

Apart from learning how to encrypt emails, you also need to follow email security best practices to keep your messages safe:
1. Use Strong, Unique Passwords
Create passwords that are long, complex, and unique for each email account. Avoid using easily guessable information like birthdays or common words. Strong passwords protect your account from unauthorized access and reduce the risk of hacking.
2. Enable Two-Factor Authentication (2FA)
Add an extra layer of security by requiring a second form of verification, such as a code sent to your phone, in addition to your password. 2FA provides an additional barrier to prevent unauthorized access, even if your password is compromised.
3. Regularly Update Your Email Software
Keep your email client and operating system updated with the latest updates and security patches. Updates often include fixes for security vulnerabilities that could be exploited by attackers.
4. Be Cautious with Email Attachments and Links
Avoid opening attachments or clicking on links from unknown or suspicious sources. Verify the sender before interacting with any attachments or links. Phishing attacks and malware are often spread through malicious attachments and links.
5. Use Encryption for Sensitive Emails
Encrypt emails containing sensitive information using built-in encryption features or third-party tools to protect the content from unauthorized access. Encryption ensures that only the intended recipient can read your message, safeguarding sensitive information from prying eyes.
6. Regularly Monitor Account Activity
Check your email account regularly for any unusual or unauthorized activity, such as unfamiliar login attempts or changes to account settings. Early detection of suspicious activity can help prevent or mitigate potential security breaches.
7. Educate Yourself and Others
Stay informed about the latest email security threats and best practices. Share this knowledge with others to improve overall security. Awareness and education help in recognizing and avoiding common threats, enhancing overall email security.
8. Use Secure Connections
Make sure you are using secure connections (like HTTPS) when accessing your email through web browsers and avoid using public Wi-Fi for sensitive communications. Secure connections protect your data from being intercepted during transmission, especially when using public or unsecured networks.
