Add check to see if submission was done correctly

[foens]

So far there is no checks in the code for errors. Sending an email with no subject is blindly accepted. What about adding a check like:

if(!request.ok())
throw new RuntimeException(request.body());

in the web() method?

I'll consider this. For now foens, you have to do the following:

String response = sendgrid.send();

You'll get a json string back. Convert that to json and parse it to do your check.
