I have a dedicated email inbox for newsletters, and for blogs that don't have a newsletter I use https://rssby.email/ to receive them. Keeps my main inbox clean and when I want to dive in, I know where to look.
Here are some of my subscriptions:
Sacra
Every.to
David Perell
Animalz
Demand Curve
Seth Godin
Eugene Yan
A Smart Bear
Benedict Evans
explaining.software
Jason Liu
...and many more that I am missing that I have move over to this dedicated inbox from my main inbox.
