What Is Encrypted Email? Why and How to Use It

Imagine sending a letter through the mail, but instead of sealing it in an envelope, you write it on a postcard for anyone to read. This is why you need an encrypted email — when you send an unencrypted email, its contents can be intercepted, altered, or even stolen.

But what does it mean when you encrypt an email? What are encrypted emails for?

An encrypted email is like locking your message in a high-tech vault, ensuring only the intended recipient can open it.

In a world of cyber threats, data breaches, and surveillance, encrypting emails isn’t just a luxury — it’s a necessity. Whether you’re protecting sensitive business communications or safeguarding personal data, encryption helps keep prying eyes out.

In this guide, we’ll break down different email encryption methods, including PGP, S/MIME, and TLS, explaining how they work and when to use them. By the end, you’ll have a clear roadmap for securing your email communications.

Let’s begin by understanding: What is encrypted email?

What is Encrypted Email?

Let’s first define encrypted email: An encrypted email is a secure email that only the intended recipient can read.

With the encrypted email definition out of the way, let’s now understand what does encrypt email mean in plain English.

Unlike regular emails, which are sent in a plain format, encrypted emails are scrambled using a code or a cipher. Only the person with the key to decipher the encryption can read the content. This way, the information stays confidential even if someone steals the email during transmission.

You might have stumbled upon the term “encrypted email” because of a new workplace policy or a standard in your industry. While the idea of encrypting your emails might sound intimidating, it’s more approachable than you think.

Did an office colleague ever ask you, what is encrypted email means? Now you know — encrypting an email is a safe way to send sensitive information.

Why Send Encrypted Email?

Email services such as Gmail and Yahoo keep improving their security and spam protection mechanisms — case in point, the recent Yahoo and Google Gmail spam update.

Mailbox providers already offer encryption services to keep your messages safe as they travel from your computer to their servers. They do this using a protocol called TLS, which makes sure nobody can peek at your message while it’s on its way — more on the SSL or TLS encrypted email protocol below.

However, once your email reaches the service provider’s email servers, the TLS protection goes away, and your email sits there in a readable, plain, proper email format. So, if someone gets access to these servers, they may be able to read your email easily.

What’s more, this plain text email isn’t just accessible from your account but also from the recipient’s account. So, if someone steals your or the recipient’s password, they can read the email without any problem.

Unencrypted emails are also pretty easy to forge. Hackers can fake an email and make it look like it came from a legitimate source — also called email spoofing.

That’s why relying on basic protection won’t be enough in some situations. Instead, you need to apply end-to-end encryption. Your email is encrypted right on your device and stays encrypted while it’s on the server until it reaches the recipient’s device. This is the purpose of encrypted email in our daily lives.

Understanding Email Encryption

You don’t have to encrypt email address, only the email content.

Without encryption, sensitive data — like financial details, business plans, or personal conversations — can be intercepted and misused. Email encryption is a crucial safeguard for maintaining privacy in an increasingly digital world.

Let’s explore why encryption is essential — not only for securing communications but also for complying with regulations that require businesses to protect user information.

Here are scenarios where we recommend using end-to-end encrypted emails for extra email security.

Protect Sensitive Information

When sending certain types of information through email, you want to be extra careful. No one wants their medical records or IDs leaked. This is a scenario where using encrypted emails can add that extra layer of security to keep your information safe from people who have no business seeing it.

But when should you encrypt an email message?

Use encryption when sending these types of information:

Medical records.
Employment records.
Financial documents.
Bank account details.
Insurance information.
Social Security numbers.
Personal Identification Information.

Compliance With Regulations

Apart from just keeping personal stuff safe, there’s another big reason why encrypting emails is important: staying on the right side of the law. Regulations for encryption can be specific to an industry or a region. For example:

In the European Union, the General Data Protection Regulation (GDPR) recommends companies use encryption to store and transfer personal data because they’ll be held accountable in case of a breach.
Canada has the Personal Information Protection and Electronic Documents Act (PIPEDA), which states organizations must have security policies and tools, such as encryption, to protect the personal information they collect.
Australia’s Privacy Act has similar requirements for organizations and businesses.

Now, besides countries having rules, certain industries have their own set of rules, too.

Here are a few regulations for industries in the United States:

Industry	Regulation Name		Requirement
Healthcare	Health Insurance Portability and Accountability Act (HIPAA)	Department of Health & Human Services	Emails containing patient info must be encrypted to keep people’s health details private.
Finance	Gramm-Leach-Bliley Act (GBLA)	Federal Trade Commission	Financial institutions should encrypt emails to protect customer financial information.
Legal	Various State Laws	State Governments	Lawyers often need to encrypt emails to keep client information confidential.
Education	Family Educational Rights and Privacy Act	Department of Education	Schools should do everything in their power to keep student records private.

Privacy regulations in the US

If you’re in a different field or another country, check whether there are any rules about encrypting emails. One way to do this is by talking to your company’s legal staff or a compliance officer.

You could also search online or check with professional organizations in your field. They often have guidelines or resources on these topics. If you want to be thorough, contact a local regulatory agency or a lawyer who knows about information security laws.

What Does Standard Encryption Mean

When discussing “standard encryption,” it’s important to understand that the term refers to two related but slightly different concepts.

1. Data Encryption Standards (DES)

Historically, this refers to the Data Encryption Standard. DES was an early, widely adopted symmetric-key algorithm. However, due to its relatively short key length, it’s now considered insecure for modern applications.

While DES itself is largely obsolete, its influence on the development of modern encryption is significant.

2. Modern Encryption Standards

In a broader sense, standard encryption refers to the current, widely accepted and implemented encryption algorithms and protocols used to secure data. So a standard encryption email would be encrypted using S/MIME and would travel between servers using TLS.

These include:

Advanced Encryption Standard (AES): This is now the prevailing standard for symmetric-key encryption. It’s considered highly secure and is used in a wide range of applications.
Transport Layer Security (TLS): This is the standard protocol for encrypting communication over the internet, ensuring privacy and data integrity. When you see “HTTPS” in your browser, it means TLS is being used. It helps create an encrypted email connection between servers.

Modern versions of TLS, such as TLS 1.3, are considered standard for secure internet communications.

When people talk about standard encryption in modern contexts, they are generally refering to the use of strong, current encryption algorithms like AES, and secure protocols like TLS.

What Does the Process of Email Encryption Involve?

The process of email encryption involves scrambling the contents of an email so that only the intended recipient can decode and read it.

Here’s how it works:

Encryption at the sender’s end: When an email is sent, encryption software converts the message into an unreadable format using cryptographic algorithms. This can be done using methods like PGP or S/MIME.
Secure transmission: The encrypted email travels through the internet, protected from interception. If TLS is enabled, it also secures the connection between mail servers.
Decryption at the recipient’s end: The recipient, using a private key or decryption mechanism, unlocks the email and reads it in its original form.

So even if an email is intercepted, it remains unreadable to unauthorized parties.

Do I Need Email Encryption for Personal Use?

You won’t typically need email encryption for personal emails. Personal email security is mostly a matter of avoiding risky behavior, such as sharing passwords. If you plan to send sensitive data, like medical or financial records, password-protect these files and send them as an attachment.

Or you can use more secure methods like secure messaging platforms or a secure file-sharing service.

Encryption is still an option, but depending on your email client and the recipient’s client, it could need some configuration. So, only use it if you have to.

When to Use Encrypted Email

Encrypted emails should be used whenever sensitive information needs to be protected from unauthorized access or data breaches.

Here are 6 key situations where encryption is essential:

Sending sensitive business information: Encryption is essential when sharing confidential company data, financial reports, or intellectual property to prevent unauthorized access.
Protecting personal data: Emails containing personal identifiers, health records, or financial details should be encrypted to safeguard privacy.
Complying with data protection regulations: Businesses handling customer data must use encryption to meet legal requirements such as GDPR, HIPAA, or CCPA and avoid penalties.
Communicating with legal or healthcare professionals: Lawyers, doctors, and financial advisors use encryption to ensure privileged or confidential conversations remain private.
Preventing email interception: Encryption is crucial when using public Wi-Fi or sending messages over unsecured networks to protect against cyber threats.
Sharing passwords or login credentials: While it’s generally best to use password managers, encrypted email can add an extra layer of security when sharing sensitive login details.

How Do You Open an Encrypted Email?

Opening an encrypted email depends on the encryption method — the table below breaks it down.

Encryption Method	How to Open the Encrypted Email
PGP (Pretty Good Privacy)	The recipient needs a private key and a PGP-compatible email client (such as GnuPG or ProtonMail) to decrypt and read the message.
S/MIME (Secure/Multipurpose Internet Mail Extensions)	The recipient must have an S/MIME certificate installed in their email client. The email will automatically decrypt if the certificate matches the sender’s encryption.
TLS (Transport Layer Security)	The email is encrypted but does not require special steps to open. If both sender and recipient use TLS-supported email services, the message appears as a normal email.
Microsoft 365 Message Encryption	The recipient receives an email with a link to a secure portal or an option to sign in with a Microsoft account to view the message. Some messages can be opened directly in Outlook.
Secure Portal-Based Encryption	The recipient must log in to a secure web portal using provided credentials or a one-time password to access the encrypted email.

Opening different types of encrypted emails

We have detailed sections on encryption methods further below.

Never Share Passwords Over Email

There’s one type of information you should never send over email, even if you encrypt it: your passwords. While encryption makes your emails a lot safer, it’s not a fortress. If someone really wants to and has the right tools, they might still find a way to crack it open.

Instead, a safer alternative is to use a password manager — an app that keeps all your passwords in a secure vault, locked with a master password. Password managers also let you share passwords securely without the risks that come with using email.

Next, we go deeper into the encrypt email meaning. If you’ve ever wondered what happens when you encrypt an email, the next section has answers.

Encrypted Email Guide

Now you know whats an encrypted email — but how does it all come together?

Before explaining the details of sending and receiving encrypted emails, we should cover a few concepts and protocols. This way, you can make better choices based on what you learn.

Encryption Keys

Adding Encryption to Thunderbird — Adding encryption keys in Mozilla Thunderbird

The best way to encrypt email is to use an encryption algorithm and a key. The algorithm is fixed. It always goes through the same steps. But the keys are variable, meaning each key will produce a different result.

The key determines the unique output of the encryption process. Even a slight change in the key will result in a completely different encrypted message. It’s the secret component that ensures only authorized parties can access the original, unencrypted information.

Encryption keys come in two types:

Public key: A public key is like a lock, and it’s called public because anyone can have it. When someone wants to send you an encrypted email, they use your public key to lock or encrypt it.
Private key: The private key is like the key to that lock. It’s called private because only you should have it. You use your private key to unlock or decrypt the email so you can read it.

An email locked with your public key can only be unlocked with your private key, and vice versa. Communication is facilitated by an encrypted email key exchange.

You can encrypt email communications in two ways: the connection that transports the email and the email message itself. Connection encryption is known as transport-layer encryption while encrypting the message itself is called end-to-end encryption.

Email Encryption Protocols

Email encryption protocols are the foundation of secure digital communication.

They establish rules and methods for encoding email content, transforming it into an unreadable format during transit and storage. These protocols ensure that only authorized recipients can decipher the message, safeguarding sensitive information from prying eyes.

What Does Email Use for Encryption?

Email encryption primarily entails the use of these 4 protocol types:

Transport Layer Security (TLS),
OpenPGP (Open Pretty Good Privacy),
Secure/Multipurpose Internet Mail Extensions (S/MIME),
Proprietary Encryption Protocols.

Transport Layer Security (TLS)

TLS encrypts data packets that travel between your device and the server so that no one can read them, even if they can eavesdrop on your connection. But the encryption isn’t end-to-end — the server that receives the packets decrypts them.

The protocol works automatically, meaning you don’t have to install any special software to use it. But a lot goes on behind the scenes. When you want to send an email to a server, a process known as the TLS “handshake” kicks into action to establish a secure connection.

Here’s a simplified breakdown of what happens:

Initiating the connection: Your client or browser sends a secure connection request to the server.
Server certificate: The server responds by sending over a digital certificate. This certificate, issued by a trusted entity called a Certificate Authority (CA), vouches for the server’s identity. It’s the server saying, “You can trust me; see, I have this certificate!”
Verification: Your client checks the certificate to make sure it’s valid and really from the intended server. This is your device’s way of making sure it’s not talking to an imposter.
Key exchange: Your device and the server exchange key information to establish a secure connection. This is like exchanging secret handshakes so that both sides can understand each other, but anyone eavesdropping wouldn’t understand a thing.
Secure communication: Your data is encrypted using this key information, sent to the server, decrypted by the server, and vice versa. This ensures that your communication remains private and intact.
Closure: Once the communication is complete, the secure connection is closed. If you or the server want to communicate securely again in the future, a new handshake process will begin.

If you know anything about secure connections, you’ve probably heard about Secure Socket Layer (SSL). It was the go-to protocol for establishing secure connections, but TLS replaced it a few years ago. Despite the transition, many people still use TLS and SSL interchangeably.

OpenPGP

Open Pretty Good Privacy is the most popular standard for end-to-end email encryption. It was first developed in 1997 as a proprietary protocol, but it became open-source a few years later. It provides a set of rules for application developers to follow when creating email encryption software. Various versions of OpenPGP are available for all the major operating systems.

Here’s how OpenPGP works. Your email software generates an exclusive pair of public and private keys. When you want to send an encrypted email, it uses the recipient’s public key to encrypt the message. Once the recipient gets your email, they’ll use their private key to decrypt the message into readable text.

To use OpenPGP on your computer, you’ll need an encryption program, such as Pgp4Win if you’re a Windows user or GnuGP if you’re into Linux. You’ll also need a certificate manager, like Kleopatra. The process involves a few imports and exports and might feel overwhelming at first. But you can set everything up in less than 30 minutes.

How do you find the recipient’s public key?

The easiest option is to ask them to send it to you. They can email you the text file containing the public key. Doing this doesn’t pose a security risk since the key is literally “public.” The other option is to search their email address on a key server, a directory of public keys. But there’s no guarantee you’ll find the public key.

Here’s a list of certificates you’ll find on Kleopatra’s key server:

Digital signatures

GPG Suite is a software that helps implement PGP on Apple machines

Besides encrypting emails, OpenPGP also allows for digital signatures — a way for the sender to prove that the email came from them and wasn’t tampered with along the way. When you send an email, OpenPGP can create a unique signature using your private key. The recipient can use your public key to check the signature and verify the email came from you.

Secure/Multipurpose Internet Mail Extensions (S/MIME)

S/MIME was created by RSA Data Security, Inc

S/MIME is an end-to-end encryption protocol that encrypts the email’s text and attachments. It’s a newer standard than PGP, and it’s easier to use because most email clients, like Outlook and Apple Mail, support it out-of-the-box. So, there’s no need for additional software.

S/MIME is a corporate-friendly option because it’s an efficient, open standard that anyone can implement into their email infrastructure. So, organizations can set their network to automatically encrypt all emails end-to-end.

Proprietary Encryption Protocols

Many companies create their own encryption protocols to better control security or tailor the encryption process to their specific needs.

For example, Microsoft’s Office 365 Purview Message Encryption lets Office 365 users send encrypted emails to all addresses using this end-to-end encryption protocol.

This protocol is much more convenient than OpenPGP because it doesn’t require installing software or certificates — just ticking a checkbox. If the recipient uses Office 365, they’ll view the email regularly, but if they use another client, they’ll get a link that explains how they can access the message.

Encrypted Email Example

MIME on Gmail — MIME details in the email code

Check out the source code for this email from our Gmail Primary Inbox.

Gmail supports S/MIME encryption. This method uses digital certificates to encrypt email content, providing end-to-end security. When S/MIME is enabled, emails are encrypted before leaving the sender’s device and can only be decrypted by the recipient with the matching private key.

This ensures confidentiality and protects sensitive information even if the email is intercepted during transit.

How Do I Know if an Email Is Encrypted?

Different email clients have their own ways of showing you if an email is encrypted, but many use a padlock icon as a visual indicator.

For instance, if you’re using Gmail — client and webmail — click on the small arrow near the “To” line, and a box will pop up showing you some security details.

A red padlock means the email isn’t encrypted.
A gray padlock tells you that the email has TLS encryption.
A green padlock means the email is encrypted using S/MIME.

Here’s an example:

If you’re using Outlook, you can find similar information in the same place, but instead of colorful padlocks, it uses descriptive text to tell you about the encryption status.

With other clients, you can usually find this information in the documentation or help section of your email client. Look up “encryption indicator” or something similar, and you should find instructions on how to check the encryption status of your emails.

What Does It Mean When an Email is Encrypted?

When an email is encrypted, it’s locked with a digital key that only the intended recipient can use to open it. Even if hackers or snoopers intercept the message, all they see is unreadable code. This extra layer of security keeps sensitive information private and helps meet legal data protection requirements.

Are All Emails Encrypted?

No, not all emails are encrypted.

While many email services use TLS to encrypt emails in transit, this doesn’t guarantee end-to-end encryption. Therefore, emails stored on servers may not always be encrypted.

Also, if either the sending or recieving server does not support TLS, the email will not be encrypted in transit. True end to end encryption requires the use of S/MIME, or other similar encryption methods.

Next, let’s understand unencrypted email meaning.

What is an Unencrypted Email?

An unencrypted email is essentially a message sent in “plain text.” This means that the content of the email is readable by anyone who intercepts it during transmission.

Without encryption, the email’s content, including any sensitive information, is exposed. This makes it susceptible to interception by unauthorized parties. Unlike encrypted emails, which scramble the data into an unreadable format, unencrypted emails offer no protection against eavesdropping.

Sending unencrypted emails can lead to privacy breaches, data leaks, and potential legal consequences, especially when dealing with sensitive information.

The table below compares encrypted vs unencrypted email, highlighting their key differences in security, privacy, and authentication:

Feature	Encrypted Email	Unencrypted Email
Security	High (protected from interception)	Low (easily intercepted)
Data Privacy	Message content is unreadable to unauthorized users	Anyone who intercepts can read it
Authentication	Verifies sender identity (via digital signatures)	No built-in sender verification
Common methods	S/MIME, PGP, TLS encryption	Plaintext email (no encryption)

Opening an encrypted email varies depending on the encryption protocol and whether your email client supports that protocol.

For example, if an email is encrypted using S/MIME, and you’re using an email client like Outlook, which supports S/MIME, the process should be straightforward. If your email client is set up correctly with your private key, the authentication and decryption process happens automatically. You’ll just open the email as you normally would

To understand the exact way your email client handles encrypted emails, check its documentation.

What Does Encrypted Email Mean for You?

For most users, encrypted email means added security and privacy, ensuring that messages stay protected from hackers, surveillance, or accidental leaks. While casual email exchanges may not require encryption, it’s useful when sharing sensitive information like financial details or legal documents.

However — email marketers, businesses, healthcare providers, lawyers, and anyone handling confidential data should take email encryption seriously.

Now that you know understand encrypted email meaning, here’s how to send one.

How to Send an Encrypted Email

You can take two different routes when you want to send an encrypted email: encrypt the entire email or only encrypt the sensitive info and send it as an attachment. Let’s break down each one:

Using an Email Client

Thunderbird for Mac — Thunderbird supports PGP encryption on Mac

Sending an encrypted email involves a few steps, and the process can vary depending on the email service or client you’re using.

Here’s a brief outline of how you might go about it:

Choose an encryption protocol: Your choice might depend on your email client and whether you’re sending to recipients within your organization or outside of it.
Get the necessary keys/certificates: For S/MIME, you’ll need a digital certificate from a Certificate Authority (CA). For PGP, you’ll need to create a key pair and might need the recipient’s public key.
Configure your email client: Set up your email client to use the chosen encryption method. This might include installing additional software or configuring built-in settings.
Compose your email: Write your email as you normally would.
Encrypt the email: If you’re using S/MIME, your email client will automatically encrypt the email when you send it. With PGP, you might need to use a plugin or an external program to encrypt the email before sending it.
Send your email. The recipient will need the corresponding private key to decrypt and read the email.

How to Send Encrypted Email - What You Need to Know

Encrypted Attachments

You should always encrypt emails and their attachments.

But in a tight situation, you can encrypt only the attachment using a file encryption software or service. You then attach this encrypted file to your email. The recipient will need the correct key or password to decrypt and access the file.

This method is usually simpler since the sender and recipient don’t have to have compatible email encryption setups. Also, the email itself is still readable so that the recipient can understand the context of the attached file.

Here’s how you can encrypt a text message (or any kind of file) using OpenPGP.

Download and install the right OpenPGP software for your operating system.
Create your keypair using your name and email address.
Click Encrypt and choose your file.

What is encrypted email and how to encrypt it — Click encrypt and choose your file

If you want to encrypt the attachment using someone else’s key, import their certificate file. Otherwise, leave your own certificate selected and click Sign/Encrypt.

You’ll get a pgp file, which you can attach to a regular email and send to your recipient.

You’ll need a different way, such as file sharing, to securely share the decryption key with the recipient. Still, if someone intercepts both the email and the decryption key, they can access the sensitive content in the attachment.

Email Encryption Best Practices

Email security isn’t just about which encryption protocols you use. As the person in the driver’s seat, how you handle encryption matters a lot. Here are a few tips to maximize your protection:

Keep your private key files on a secure drive or folder, and never share them with anyone. Cloud storage or printed keys.
Make it a habit to encrypt all your emails if you decide to go down the encryption path. Encrypting everything makes it difficult for someone to spot which emails might contain sensitive information, adding an extra layer of security.
For maximum security, don’t keep unencrypted versions of your encrypted attachments on your device. This way, your sensitive information will stay safe even if someone gets access to your device.
Keep your email client and encryption plugins up-to-date to get the latest security enhancements.
Learn about email encryption and educate others who may need to send or receive encrypted emails.

What Does Encrypted Mean in Email Marketing?

It’s marketing — what’s an encrypted email got to do with it?

Well, email encryption in marketing ensures sensitive data remains protected from cyber threats. Since email marketers handle large volumes of personal and business data, encryption helps prevent unauthorized access, data breaches, and compliance violations.

Ignoring encryption can put both brand reputation and customer trust at risk.

Here’s why email marketers should take encryption seriously:

Protecting customer data: Email campaigns often contain personal details like names, email addresses, and purchase history. Encryption ensures this information isn’t exposed to hackers or unauthorized third parties.
Ensuring regulatory compliance: The GDPR Com p liance Checklist and CAN-SPAM require businesses to safeguard customer data. Encrypted emails help meet compliance standards and avoid hefty fines.
Preventing phishing and spoofing: Cybercriminals often intercept and manipulate marketing emails for phishing scams. Encryption, combined with authentication methods like DKIM, SPF, and DMARC, helps prevent email spoofing.
Securing internal communications: Marketing teams exchange strategy documents, customer lists, and email campaign reports via email. Encrypting these emails protects valuable business data from leaks.
Maintaining brand trust: Customers expect businesses to handle their data responsibly. A security breach due to unencrypted emails can damage trust and hurt your brand’s reputation.

By integrating encryption into email marketing practices, businesses can maintain compliance and gain customer confidence.

Always Clear, Sometimes Encrypted

An encrypted email is your digital safeguard when sending sensitive information. It transforms your readable message into a scrambled text, which only the recipient can unscramble and read with the correct key.
