Interpreting incoming emails

Okay, this is a long shot, but I could use a hook where to start looking.

I've been looking for ways to do easy integrations with common calendars. Think Google Calendar or Outlook. I want read access to know when certain events are starting. So I've started building integrators with League's Oauth. It gets complicated quick (what events, how to process changes, etc).

So I thought off adding a virtual participant. This way it's service agnostic, and always up to date.

But how?

I'm on AWS, I use SES and have some SNS notifications set up. I've read AWSs documentation, and my use case should be possible. Retrieve the mail, forward it to my web hook.

How can you interpret the email? Anyone with any ideas? I'm all ears!
