Countdown Timer inside of outgoing email?

This question appears to have been answered on the old forums (phplist forums • View topic - Countdown timer RESOLVED) but it’s no longer archived for me to view.

In my newsletters, I currently announce coupons that “expire in 48 hours.” However, I’d like to actually have a countdown so that whenever people open the email, they’ll actually see a countdown timer informing them of how much time is left (only 23 hours left, etc).

I have this functionality on my actual website to do it (via javascript) but didn’t know how to implement it inside of the phplist recipient email.

Can you point me to the direction of any plugins or past threads which would allow me to do this?

Nevermind - I found an alternative solution through a third party to embed timers into our email messages.
