Even though email communication has become a vital tool for both personal and professional connection, email security remains a key concern due to the increase in cyberthreats and vulnerabilities. The typical email system lacks mechanisms to ensure secure transmission, sender authenticity, and data integrity. As part of a blockchain-based solution to these issues, this research provides a decentralised platform for secure storage, encryption, and email verification. The suggested approach ensures the safe delivery, authentication, and validation of each email by utilising a tamper-resistant blockchain ledger. Unauthorised access or modifications are impossible because the email's content, and the metadata are stored on a distributed network. The system offers an open way to monitor email exchanges and uses smart contracts to expedite the validation process. In order to reduce the possibility of spoofing, phishing, and other cyberattacks, this study aims to demonstrate how combining blockchain technology with email systems might increase security, privacy, and integrity.
