Get notified functionality when it's a digital downloadable product

I'm soon launching a collection of digital downloadable products, and I want to use a Wishlist or "get notified when this digital product is available" but can't seem to figure out how to do this? If I create a digital download product - I don't get to save or publish this product unless I include a downloadable file. 

I tried using the "service" product option, but then I got stuck when I have to manually fulfill every order. Any suggestions are much appreciated.

You cannot do this for digital products because, as they are digital, it is assumed they are always available. As a workaround, you can manually add a Newsletter Block on a layout page to collect details of visitors who are interested.

Thanks, Paul! I actually just figured out a way that works by using the service product, + immediately sending out an email including the link to the digital download. I hope I haven't overlooked anything.😅

Can you explain further - for the benefit of anyone reading this thread?

As for the digital products (created as services) that are currently in stock, I created an automated email that immediately goes out to customers upon their purchase. This email contains a direct link to their file.

Thanks for sharing your workaround for others. One thing to bear in mind is that your download link will remain live, so if someone shares the link online, anyone who clicks it will be able to download a copy of the asset (passwords can be shared in posts too).

The good thing about digital download products on Squarespace is that a different download link is generated for each sale, and each link expires 24 hours after the purchase.

That's a great point, Paul! 
In my case, it's not a problem, but for others it might be - yes.
