Targeted Emails by Products Ordered

[jsciabica]

I need to be able to target customers who ordered a specific product with a marketing email.  The Shopify Email app uses Customer filters for targeting, but there are no filters for products ordered.

1) Is there some workaround?  If I have a CSV list of email addresses, can I somehow create a list to use with Shopify Email?

2) Are there any plans for more filters in the Customers view?  Specifically, products (or collections) ordered but also being able to target based on marketing campaign interactions is pretty crucial.  For instance, target anyone who opened or did not open the previous campaign.
