The Impossibility of Sending Material Through a Wormhole

If wormholes exist and can be artificially created, could they be used for interstellar communication if physical travel through them proves impossible? That's tricky because there's a possibility with the wormhole that you could send material through. It's one of those things that what type of impossible are we talking about here? Also why can't I send a copy of someone's mind through? If I can scan someone digitally, why can’t I send that through too? We looked at more on our teleportation episode.
