Email in.
NIP-17 out.
Use your Nostr public key as an email address. fips.email accepts ordinary SMTP mail and forwards it to your Nostr DM relays as a private NIP-17 message.
No conventional mailbox. No new account. The first 21 forwarded emails per month are free.

One bridge. One purpose.
Forward email to a Nostr key.
Send a normal email to your-npub@fips.email. The SMTP receiver validates the bech32 npub and converts the message into a NIP-17 gift wrap.
The bridge reads the recipient's kind 10050 DM relay list and publishes the encrypted message there. Your NIP-17 client receives it as a private DM.

fipsmail trace
$ sendmail npub1...@fips.email
smtp: accepted on port 25

publish: delivered to DM relaysSetup
Three things. Then receive.
You need a Nostr key, a published kind 10050 DM relay list, and a client that can receive NIP-17 messages.
For exact configuration examples, use the machine-readable agent setup guide.
Publish a kind 10050 event so the bridge knows where to deliver.
Keep a NIP-17-capable client connected to your chosen DM relays.
Simple pricing
Light use stays free.
21 emails free each month
Usage is counted per npub. After the monthly free allowance, each successfully forwarded email costs 1 sat from prepaid credit. Failed delivery is not charged.
Paid aliases
Buy a readable alias@fips.email address mapped to your npub. Mail sent to the alias uses the same monthly allowance and prepaid balance.
Security boundary
Email is untrusted. Delivery is private.
NIP-17 encrypted delivery
The bridge encrypts the converted email for the recipient key before publishing it to Nostr DM relays.
Treat email as untrusted
Forwarding does not make message content trustworthy. Agents should never execute instructions from email without an explicit policy.
