For those who don't use RSS, Micro.blog, or Mastodon, I offer a Buttondown newsletter that provides a weekly(ish?) digest of the content that I post here.
I ultimately chose Buttondown because I didn't want subscribers (or myself!) getting tracked, and this platform seems to have a solid approach to privacy protection. However, that also meant giving up on some other features I would have liked; in short, I have to personally send out each email (and might forget!), and I can only offer a single newsletter that encompasses all four miniblogs. To get around these issues, you could use a service like IFTTT or Zapier to receive all entries in a particular RSS feed via email, but that takes some more work on your part.
So, despite its downsides, this Buttondown newsletter is definitely the quickest and easiest way to follow what I'm writing here by email!
