A system for securing data and information transmitted via entails is disclosed. The system includes a sender-side device from which an email including a first code is transmitted. The first code comprises instructions for manipulating server-side processing of the email. The system includes a filter module which determines whether the first code is present within the email, and subsequently transmits the email to a processing server in case if the first code is present within the email. The system includes a processing server which processes the email in accordance with the instructions specified in the first code and generates a first link, thereby enabling the email sender to access and modify the access policy for the email. The processing server further authenticates the intended recipient of the email via an OTP before enabling the intended recipient to access the parts of the email.
