Custom Emails per Product?

I just installed the demo and it does not look like this can be done, but thought I would check here. I would like to be able to send custom emails to customers based on the product(s) they purchase. A lot of our products are e-delivery from our suppliers and I would like to be able to inform customers about the process, time for product delivery etc.

Is there any way to do this or any workarounds? If not, would it be expensive to have custom programmed? I imagine it being an option when creating a product to be able to send a separate email or add a clause at the bottom of the order confirmation email.
