I am hosting this on Substack (https://substack.com/) which was free to get started in minutes. I was able to buy and add my own domain later as well.

If I were starting from scratch today I would choose Beehiiv (https://www.beehiiv.com/ ) over Substack. They just seem to care more and are more or less the same but adding features much quicker.

I am moving to a custom setup soon but the above options are very useful in getting something off the ground.
