Abstract: This paper presents a novel approach to secure email services using Elliptic Curve Cryptography(ECC). With the increasing reliance on email communication for both personal and business purposes, ensuring the confidentiality and integrity of email messages has become paramount. Traditional email encryption methods, such as RSA, often suffer from computational overhead and key management challenges, making them less practical for widespread adoption. The pro-posed approach leverages ECC with Diffie Hellman Cryptography, a more efficient and secure cryptographic algorithm, to provide robust encryption and authentication for email messages. ECC offers shorter key lengths compared to RSA, resulting in faster encryption and decryption operations while maintaining a high level of security. Additionally, Diffie Hellman is well-suited for resource-constrained environments, making it ideal for use in mobile devices and other low-power devices
