I have newsletters, a few of them.
The main one is called the Letters of Clio.
The Letters of Clio is a behind-the-scenes look into the life of Clio. (That's me.)
While the blog posts are more serious, the newsletter is a bit sillier, more personal, and less sculpted. If the blog is the equivalent of a carefully crafted and rehearsed stand-up show, the newsletter is the small, private club where I try things out.
The topics remain similar, however. In one sentence:
„Essays on being human with a pinch of philosophy and a dab of science.“
It's irregular, though normally published on Thursdays, sent to your inbox with love, sweat, sometimes blood, and a lot of self-irony. (Click the banner below to sign up.)

Of course, it wouldn't make sense for you to sign up without knowing what you can expect, right? So here is a (manually updated) archive of past issues.
Past issues

Hope to send something to you soon.
Then there are two additional ones. These are mostly recaps of the other content going to my blog:
Tsundoku is the email list for my monthly book summaries.
And the one called kvn.li is all the blog posts sent by email, as soon as I publish them. (However, the Letters of Clio are NOT sent to this list.)
I sometimes also publish a pop-up newsletter. I will announce them in Letters and on the blog. They will run for a fixed time period and then be sent to the nether realm, the list deleted, and no subscriber moved. It's how I plan to do silly projects.
