My blog is at the link, but I wanted to use my rec to highlight RSS again. Most blogs today offer newsletters to keep up with posts. I respect email. It's a backbone of the internet. But I loathe newsletters junking up my email inbox.
My preferred way to keep up with blogs is with their RSS feed (Real Simple Syndication). Nearly every website has an RSS feed. Podcasts would not work or exist without one. If you've subscribed to a podcast, you subscribed to an RSS feed.
You'll need an RSS Reader or service to subscribe to a blog's RSS feed. Think of it as a podcast app but for reading.
NetNewsWire is a fantastic free app for Mac and iOS that's perfect for getting started. Feedly is a good platform agnostic option with web, iOS, and Android options. I haven't used it in like a decade though. Another option similar to Feedly is Inoreader that I haven't tested myself.
I personally use Reeder.
RSS readers also aren't just for following blogs. YouTube channels have RSS feeds. So do Twitter profiles. Tumblrs. If there's something you want updates on and it has a RSS feed, you can toss it in a reader.
