Adding a Subscription Center Link to Templates

Happy Monday!

I am trying to add this language from a NetSuite Subscription Management Center Copy/link to all of our email templates. I have tried a couple of different ways, but no matter what template I put it into, the subscription center link does not work.

Is there a certain link I should be using? I got this verbiage/link from a system-generated Confirmed Opt-in.
