Having a problem with a seller

[Jerel Lyons]

gonna make this short, I posted a house that I have under contract on Craigslist,I got a text from a buyer that was supposed to meet me at the home yesterday, I showed up he didn't, he claimed that he forgot, (whatever right?) and he asked me to send over the contract Through Email, Now I've never done a deal before, am I risking anything if I email him a contract (with my fee tied in of course) how would that go?what does he need to understand if I decide to send it to him, or is there another way to go about this?
