Hello Florian,
If you need a new challenge or add features to existing SNIP plugin, I suggest you to take a look to email markup which is very related to schema.
I’m particularly interested of adding this to Email orders coming from woocommerce

Some interesting article about the use and possibilities

Hey Goncalo,
well, it’s a very nice idea but SNIP was made to create structured data for your website, not for E-Mails 😉
Exactly, there is nothing out there for emails, so I see opportunity for a new plugin!
think about it 😉
