Dynamically add date to email in a nurture program

Hello,

I'm looking to add an expiration date that is dynamic based on the date the email is sent in an automated nurture program. Lets say 30 days after the send date. I tried using JavaScript in an ADC block, but it must be pulling out my script when the email sends.

Is there any way of adding dynamic date text to an email within Eloqua?

Thanks for your help.
