Email rules

Hi,
Fantastic plugin, so easy to use.

I was wondering if you may consider an addition for the future release.

When a customer checks out on our site, then can choose ‘Click and Collect’ instead of paying for postage, which is now proving very popular. The issue is, there is no way to send a different email to customer who selected this instead of Delivery, so they all get the ‘Your order has shipped’ email.

Would it be possible to add an option to the ‘Rules’ section for shipping type, so we could then send a different email to those customers and could therefore amend the heading to something like ‘You order is ready for collection’

Many thanks
