If you do anything to correct the situation, you are reinforcing the bad behavior, and it will continue to happen with greater frequency.
You actually get punished more for trying to do the right thing.
You should just delete them, mark as spam, etc.
From a behavior stand point you would want to avoid reinforcing the behavior, and possibly also identify a way to punish the behavior -- one could do the wrong thing and publish them online, which might be a punishment (while probably technically legal, this behavior could increase the frequency with which you interact with lawyers).
In my case, someone has the same name modulo middle name, and his gmail is one character more than mine, so I get a few of their emails a month, at first I tried to respond to the sender, or forward them along, but it just kept happening so I now I delete them or mark them as spam.
