How to send and receive emails with the Nostr Mail client.

The inbox shows all received emails:

• Emails are sorted by date (newest first)
• Tap an email to view details
• Pull to refresh for new emails

New emails appear automatically as they arrive via Nostr relays.

1. Tap the compose button (+ icon)
2. Fill in the recipient
3. Add a subject
4. Write your message
5. Tap "Send"

To send to regular email addresses (Gmail, etc.):

1. You need a bridge account (e.g., you@bridge.mail)
2. Your "From" address determines which bridge to use
3. The bridge forwards your email via SMTP

From: you@bridge.mail
To: alice@gmail.com

• Relays only see encrypted blobs
• Your private key never leaves your device
