Is there an app for reading newsletters?
Is there some website that I could use to subscribe to newsletters? Something that would give me an email address that I could use to subscribe to newsletter, and that would then automatically organize them according to topics. Maybe even some kind of built-in bookmarking tool would be great and subscription management (unsubscribe, find similar content). Something like RSS clients but for newsletters.
I would like something that allows subscribing to newsletters from different platforms.
Is there a web/service/app like that?
Not really an app for reading newsletters, but I built a SaaS[0] to forward and combine newsletters into an ebook and send to your Kindle.
I’ve been using it everyday and super happy with the experience.

I like the Substack app - for all the substack newsletters. https://substack.com/app for ios and android. And their web reader (https://substack.com/browse) is pretty good. I just wish I could plug in RSS and other syndication feeds, and make it easy to migrate subscriptions from my mail inbox to the reader.
I use Readwise for notifications with highlights from books, but they also support newsletters.
Feedly lets you subscribe to newsletter on their paid plan. To unsubscribe, you can just delete the source and I think it also shows you similar content (not sure if it works on newsletters).
Hey email service has a filter they call "The Feed" it works well enough for this, but it doesn't have the ability to make multiple "Feeds" - I would like a Feed for promotional emails, professional emails, and hobby emails - but "The Feed" shoves them all into one box. It's fine, but not perfect.
You've pretty much described gmail / most webmail providers.
You can use whatever+tag@gmail.com for labels, and set up rules for tagging, folders, etc.
Matter might be what you’re looking for. They basically give you an email address to submit for newsletters but things addressed there end up in a feed inside the Matter app.
I use Mailbrew to read my newsletters. They give you an email address you can use to sign up to newsletters.
meco.app is an app for newsletters.
Not sure it has the features you describe though, it's on my list to checkout
