Does JavaScript Work in Email Clients Today?

JavaScript Support in Email Messages

The question of whether JavaScript is supported in email messages is a contentious one. While some older email clients like Lotus Notes, Mozilla Thunderbird, Outlook Express, and Windows Live Mail supported some form of JavaScript execution, modern clients have largely abandoned this feature.

According to a comprehensive comparison of email clients on Wikipedia (http://en.wikipedia.org/wiki/Comparison_of_e-mail_clients), none of the major providers currently support JavaScript execution in email messages. This includes popular webmail services such as Gmail, Yahoo Mail, and Outlook.com.

The security concerns surrounding JavaScript in email messages have been a major factor in its decline. Malicious code could potentially exploit vulnerabilities in email clients, giving attackers access to sensitive information or control over the user's computer.

While the lack of JavaScript support may limit some aspects of email interactivity, it is ultimately a positive step towards protecting users' privacy and security. It is unlikely that JavaScript will make a substantial comeback in email messages, given the significant risks involved.
