Don’t know if people know of this site or not but just in case you don’t, it’s pretty damn good. All they require is an email address (I used an anon one with no issues). You can follow up to 100 authors and get alerts when new stuff is announced and published.

It’s also got a decent future search, showing up everything being published in the next 7 or 30 days which you can also narrow by genre.

They do use Web Beacons on their site and in their emails but uBlockOrigin will handle the website and DDG Email Protection can handle the emails.
