While you can technically send sensitive information through email, it is generally not recommended unless you take additional security precautions. Standard email services, especially those that do not use encryption, are vulnerable to interception and unauthorized access. Here’s an overview of the risks and precautions you can take if you must send sensitive information via email:

Risks of Sending Sensitive Information via Email:

1. Lack of Encryption: Most email services do not encrypt the contents of the email by default. This means that if someone intercepts the email, they can read its contents.
2. Email Account Breaches: If your or the recipient’s email account is compromised, sensitive information could be accessed by unauthorized individuals.
3. Phishing and Spoofing: Emails are common vectors for phishing attacks, where malicious actors impersonate trusted sources to trick you into sharing sensitive data.
4. Storage on Email Servers: Emails are often stored on email service providers' servers, where they could potentially be accessed by hackers or even the service provider in certain circumstances.

Precautions to Take When Sending Sensitive Information via Email:

1. Use Encryption

• End-to-End Encryption: This ensures that only the intended recipient can read the email. Services like ProtonMail or Tutanota provide built-in encryption for emails.
• Encrypting Attachments: If you are sending documents containing sensitive information, use file encryption tools like 7-Zip (with password protection) or WinRAR to encrypt the files before sending them.
• Use Email Encryption Tools: You can use email encryption tools like PGP (Pretty Good Privacy) or S/MIME (Secure/Multipurpose Internet Mail Extensions) to encrypt the contents of your emails.

2. Password Protect Attachments

• If you're sending sensitive files, consider password-protecting the attachments. Send the password separately via another communication method (e.g., text, phone call) for added security.

3. Check the Recipient's Email Address

• Verify the recipient's email address before sending sensitive information to avoid sending it to the wrong person.
• Be cautious of email addresses that are similar to trusted contacts but slightly altered, as they could be phishing attempts (e.g., "paypa1.com" instead of "paypal.com").

4. Use Secure Email Services

• Some email providers offer enhanced security for sending sensitive information. For example, ProtonMail and Tutanota offer encrypted email services where even the service providers cannot read the content of your messages.
• If possible, use these services instead of standard email platforms like Gmail or Yahoo for highly sensitive information.

5. Be Aware of Phishing

• Be cautious of unsolicited requests for sensitive information via email, even if they appear to be from trusted sources. Always verify the identity of the sender by contacting them through other means (e.g., a phone call) before sharing any personal data.
• Look for signs of phishing emails such as unexpected attachments, misspellings, or suspicious links.

6. Use Multi-Factor Authentication (MFA)

• Enable multi-factor authentication (MFA) on your email account to provide an extra layer of protection in case your email account is compromised.
• This will require a second form of verification (such as a code sent to your phone) in addition to your password.

7. Limit the Amount of Sensitive Information

• If you must send sensitive data via email, consider limiting the amount of information in the email itself. Instead, send a summary and provide secure means for the recipient to access the full data, such as a secure file-sharing platform or encrypted document.

8. Use Secure File Sharing Platforms

• If you need to send large amounts of sensitive data or files, consider using a secure file-sharing service (e.g., Dropbox with encryption, OneDrive, Google Drive with file-level encryption).
• Ensure that the platform uses end-to-end encryption and allows you to set password protection and expiration dates for shared links.

When Should You Avoid Using Email for Sensitive Information?

• Financial details (e.g., bank account numbers, credit card info) should not be sent through email unless absolutely necessary and secured by encryption.
• Medical records, personal identification numbers, or confidential business documents should be shared only through secure platforms designed for transmitting sensitive information.

Conclusion:

While sending sensitive information by email is not inherently insecure, it poses risks unless you take the proper precautions. Encrypting emails and attachments, using secure email services, and enabling multi-factor authentication are key steps in protecting sensitive data. However, for very high-risk information, consider using dedicated secure communication methods (such as secure messaging apps or encrypted file-sharing platforms) instead of email.
