I would really like to expand upon this.

There is a gap in the market for good book, ebook and audiobook notifications.

Even better than just email notifications, enable options for Discord, Telegram, etc.

Enabling people to specify if they want to be notified of :
-Everything from an author (this is the only option available on other sites)
-Only get a Series specific notification (some authors have several ongoing series and not everyone wants to be notified of all their other releases besides the one series)
-Separate if you want to be notified of just physical book, ebook or audiobook release

Audible is the only competitor for audiobook notification system but it is very unreliable and many people complain about it online, and it doesn't allow you to do anything but follow an author and AI is supposed to guess what you are more interested in...

The only other options online are following a particular audiobook publisher on their website/x.com/forum/reddit/newsletter/etc.

Adding this functionality could really help drive new users to the site as well!
You can search online for the many other people searching for a solution to this problem.

We'd like to do this for sure. How and when is to be determined.
