This thing that identifies your account and looks like an email but isn’t.
This is a NIP-05: https://github.com/nostr-protocol/nips/blob/master/05.md

Yep yep! https://nostrplebs.com is the first and oldest OG Nostr service.
Explain how your email offer works?
Email goes to your DMs via your Nostr address. So email sent to derekross@nostrplebs.com come to my DMs.
What about attatchments or files?
They're not supported 😩 That would be a nice enhancement though. What if attachments were uploaded to a blossom server 😮 But then you wouldn't own them... Hrm. A lot to think about.
Yes. But the UX I’m thinking about is completely reversed.
On nostrplebs you are first an npub, then you go and sign up for a NIP-05.
What if you sign up for an email service and full fledged mailbox, that also just so happened to be nostr compatible.
