Remove email signatures in tracked emails

Is there a way to strip out html signatures? We use exclaimer for very attractive visual signatures in our emails, but they get totally distorted in the Updates section and take up like 10". Is there a way to put perhaps a hidden or white series of characters at the beginning of our signature so that Monday would know to stop attaching after that?

What’s interesting is the signatures look alot better when they come through Communihub than when they come from updates. I’m guessing you are using different code for those?
