Email Explained from First Principles

I need to take some time to closely read this insanely detailed article from Kaspar Etter. It’s not my goal necessarily to understand every detail of how email works, as I’m more interested in how managing it well is an ingredient to business success, but understanding how things work is always enlightening.

Sometimes digging into the how things work of it all can be useful as well. Kinda like how reading a CSS spec can make me a little better at CSS sometimes, even if they are dense and not necessarily for authors directly. If nothing else, it can be fun. Check out this post on how internal combustion engines work and tell me you didn’t learn something.
