I'm exploring whether or not it will be possible to use 3rd party banner ad tags for the advertisers in our email newsletters.

Hello @amyloo ,
That's a great question! At this time, our system is not compatible with 3rd party banner tags and there isn't any sort of variable built into the system for cachebusting.
