Make email inbox breathe again

I’ve subscriptions to tons of newsletters. Some paid and others from network connections. Some are on Substack and others as independent content. I get through only 20% of newsletters. And my inbox keeps getting cluttered. I wanna read all, but gets lost in the inbox chaos. Is there any tool, that could index all newsletters in a single email? Perhaps categorise them based on topic. I’ve used Unroll.me. Looking for new recommendations.
