Hey @jango81 !

From what I understand, it is up to the email recipient’s email client whether or not to support Javascript, and many email clients do not for security reasons.

It may be helpful for you to share some additional information about what you are trying to accomplish to receive more help with this. For example, Shopify’s email templates do support Liquid code, so if you are trying to make some sort of conditional text or use variables, I would recommend doing this directly with Liquid instead of Javascript.
