The most frequently used email encryption techniques include **Pretty Good Privacy (PGP)** and **S/MIME (Secure/Multipurpose Internet Mail Extensions)**. These methods use public-key cryptography to encrypt email content and attachments. **Transport Layer Security (TLS)** is also commonly used to encrypt emails in transit, ensuring data remains secure between mail servers.
