Why Should I Use Encrypted Email?

Emails are a crucial part of business communication, but they’re also an excellent target for hackers. Encrypted emails help protect your sensitive information and keep it out of the hands of unwanted people.

Email encryption is the process of converting an Encrypted Email content into a code that can only be decoded by the sender’s private key. It’s a necessity for businesses that deal with sensitive data.

1. Security

Whether you are working with confidential business information or simply using email to communicate personal matters, email encryption is essential. It protects sensitive data, intellectual property and personal information from hackers or other third parties who could read your messages or intercept and copy them.

Encryption is a security feature that scrambles emails so only someone with the correct keys can read them. The most common type of email encryption is end-to-end, which renders messages unreadable while they’re in transit between sender and recipient.

To encrypt an email, the sender generates a pair of cryptographic keys and shares them with the recipient. The public key is then used to encrypt the message and the private key is used to decrypt it.

2. Confidentiality

Email is a widely used communication method in businesses. It allows employees to communicate with one another, distribute faxes and files, and even automatically respond to requests for information.

However, as an integral part of cybersecurity, emails should never be sent without encryption. This is especially important for sensitive information, as it will protect both the sender and recipient from unauthorized access.

Encryption uses public key cryptography to ensure that only the intended recipient can decrypt a message. Each person has a pair of keys, which they generate and share with others.

When sending an encrypted email, it’s vital to include the email address and key of the recipient in the subject line of the message. This is to prevent the receiving party from deleting or forwarding your encrypted email.

3. Privacy

Encryption can provide a layer of protection against data theft and malware threats, both of which are a growing concern for companies. Whether you’re communicating with an external client or working with internal employees, email encryption is the best way to protect your confidential data and communications.

Fortunately, most modern email services support encryption. For example, Gmail supports S/MIME (Secure/Multipurpose Internet Mail Extensions) as well as PGP (Pretty Good Privacy) encryption.

Both of these encryption methods are easy to use, but PGP offers a little more flexibility and control over how well your emails are encrypted. On the other hand, S/MIME relies on a central authority to select the best encryption algorithm. That means it’s less likely to be as secure as PGP, but that doesn’t mean it’s not effective.

4. Convenience

Email is an invaluable tool for companies and individuals, allowing employees to communicate and share information in a quick and efficient manner. But with a growing number of email-based threats, businesses are looking for a more secure way to protect their confidential data.

The safest way to send sensitive information is with email encryption. This can help ensure that only you can read your messages, while also ensuring that malicious third parties or over-reaching governments cannot access the data you send.

To encrypt your emails, you can follow these steps on Windows or Mac:

5. Speed

In the modern world, companies and their clients expect their collaborators to keep communications and information safe and secure. Breaches can lead to the loss of client data, business partnerships and even professional relationships. Encryption is one of the most effective ways to ensure the privacy of this information and protect it from unauthorized access.


Encryption tools are usually integrated with email servers, which means that you don’t have to worry about purchasing extra hardware pieces for your network environment. This also saves you money and eliminates the need for separate encryption software that can become expensive. The most popular encryption methods include AES, DES and Blowfish, which all encrypt information using a cryptographic key that is generated by the sender and the recipient.
