SendOwl

Digital Delivery App is robust and flexible. It lets us, a record label, pair downloads directly to physical products (so customers can buy a t-shirt or CD and immediately receive an MP3 download). It also does this right on the order confirmation page *as well as* a separate email. We can even use it to package a single on a pre-order, and update later with the full album download on release day.

And customer service is extremely timely and friendly.

Highly recommended.
