What Is an Email Encryption Service?
Email encryption services are specialized tools designed to protect the content of email messages and attachments from unauthorized access. These services encode the email's content, making it readable only to the intended recipient who has the necessary decryption key.
While anyone with an email account can benefit from these tools, they are particularly favored by businesses, professionals handling sensitive data, and individuals concerned about privacy. The primary purpose is to safeguard information from potential cyber threats, data breaches, or any unintended interceptions, ensuring the confidentiality and integrity of electronic communications.

For any secure email solution, the core functions should include:
