Sepatate customer emails from beat sales vs sound kit sales

Currently I have tracks and sound kits for sale on beatstars, and also do email marketing to promote beats and kits to customers.

Problem is, when downloading customer information to get their emails, it doesnt split up the beat sale customers from the sound kit customers. Theyre all in the same list, with no way to tell who bought a beat vs who bought a kit.

This is annoying beacause a rapper/artist isnt going to be interested in buying kits, so emailing they about that will likely make them unsub from the email list. Same thing for producers, theyre not interested in buying beats.

So it would be nice if there was a way to download beat customers separately from sound kit customers.
Or maybe in customer csv file there could be a "sale type" column, stating which was a beat sale / sound kit sale

Thanks
