A problem you'll face is that teachers probably wont be allowed to run email addresses of students through a third party site like that.
I know for definite su8ch things would be frowned on in a lot of institutions here in the UK: probs in the US too.
Another major problem I suspect your going to face is that there are quite a few full on school management systems coming into use (there is a big one kicking about that plenty of schools in the UK have but I forget the name offhand). It's kinda hard to see the advantages of a one off system like this in that context.
Dont get me wrong it's a nifty system if you can convince people to use it. But I think that might be hard.
In terms of commerical prospects that might be even tougher - will you charge per teacher? (possibly unpopular) or will you allow a school/institution to license a bulk lot of accounts to hand to it's teachers?
