I'm just so sick of every service forcing me to give out my email even if I create an alias, it's just a big pain in the ass. but being able to just give out an npub that I specifically use for shopping, or even my personal, if it's a business that I really like, and having a DM or notification that way is just So much cleaner. Thanks for moving the needle in this direction.

Totally. And great thing about nostr is how easy it it to create identities. The shop notifications i get are from an identity that took seconds to create. No annoying email sign-ups. Nostrs usefulness for building bots is entirely underestimated
