Enable a "Reply to" address that is different than the "From" address in Zapier
Allowing a "Reply to" address that is different from the "From" would GREATLY expand the power of the Zapier integration by allowing users of an application to follow the Truthful Routing clause of the CAN-SPAM while being able to receive replies.
In general, add support in the zapier integration for additional API supported parameters such as Reply-To, tag, tracking, and my-var. the o:*** the h:***

I've just run into something similar myself. I think this is a really important feature that's missing, in fact it would make sense to just have custom headers available in the action.
