However, rather than using FetchApp to deliver the free download, we recommend storing the file in your shop and sending out the link when someone signs up for your newsletter.
The workflow looks like this:
* Upload your file to your shop (instead of FetchApp).
* On the "thank you" email / page, paste the link to your file.
The advantages of doing it this way:
* Customers stay on your site.
* Shoppers get their downloads without having to go through the checkout process and wait for the FetchApp email.
* You capture their contact information for future marketing campaigns.
* Some gateways (like PayPal) don't allow $0 transactions so the shopper might not be able to checkout anyway.
