A non-transitory computer readable storage medium that stores instructions for improving security of a transaction by utilizing Simple Mail Transfer Protocol (SMTP), the instructions when executed a processor of a device of a user cause the device to perform a method comprising:

• receiving a selection of a mailto link, wherein the mailto link is displayed on a website of a vendor server;
• in response to the selection of the mailto link, performing a mail generation process, wherein the mail generation process includes:
• generating an email response message addressed to an e-commerce system,
• embedding a token to the email response message, wherein the token comprises a version frame and an email address of the user, and
• sending the email response message to the e-commerce system;
• and
• on a condition that the user is authenticated by the e-commerce system, receiving a confirmation message from the vendor server,
• wherein the user is authenticated by the e-commerce system:
• decoding the token contained in the email response message to determine the version frame and the email address of the user,
• validating the token based on the determination of the version frame and the email address of the user, and
