Does JavaScript Still Have a Role in Email Client Functionality?

Does JavaScript Have a Place in Email Messaging?

JavaScript, a popular programming language for web development, has been a subject of debate regarding its support within email messages. While the question of JavaScript's integration into emails has stirred discussions in the past, a recent exploration has shed light on the current state of support for this scripting language in email clients.

The Verdict: Limited and Diminishing Support

A comprehensive study conducted by Wikipedia and published in their "Comparison of E-mail Clients" article reveals that only a select few older email clients, including Lotus Notes, Mozilla Thunderbird, Outlook Express, and Windows Live Mail, once supported some form of JavaScript execution. However, these clients have since phased out this functionality due to security concerns.

Modern email clients, such as Gmail, Outlook, and Apple Mail, do not support JavaScript. This decision is driven by the belief that executing scripts within email messages could create security vulnerabilities or compromise user privacy. As a result, JavaScript has become largely incompatible with the email ecosystem.
