Just curious, what’s the site called?

Buddhism has some interesting takes on this. In particular, I really enjoyed The Tibetan Book of Living and Dying, written by Sogyal Rinpoche.

This means that the sender includes a list-unsubscribe header, which is supported by a lot of email clients. Not sure if StubHub does this, but it’s worth checking.

Sackboy is basically the newer version and also really good.

Looks great!
