Does JavaScript Work in Email Messages?

Is JavaScript Indeed Supported in Email Messages?

The question of JavaScript support in email messages has been raised before. While it is generally known that email messages can contain HTML and CSS, the support for JavaScript is less clear-cut.

Answer:

According to the Wikipedia page on Comparison of E-mail Clients, only older clients like Lotus Notes, Mozilla Thunderbird, Outlook Express, and Windows Live Mail have some level of JavaScript execution support. Other email clients lack this functionality.

However, it is worth noting that this support is considered questionable from a security standpoint. As a result, it is expected that even the aforementioned clients may not always offer JavaScript execution in the future.
