Letters to friends
What am I up to? What's on my mind? What did I break this time? Every month or two I send friends a letter about exactly that: some highlights, some thoughts. No schedule, it just goes out whenever there's enough to tell.
It's for people I'm actually close with, so I vet every signup myself. If we know each other, you're in :) If we don't (yet), I won't add you. Nothing personal!
You'll get one mail to confirm your address first. I only use it for these letters, and every one has an unsubscribe link.
