I have an idea for a Nostr DM-to-email service.

The service would send you an email notification whenever you receive a Direct Message (DM) on Nostr. No decrypted content—just a heads-up that you've got a message waiting for you in your Nostr client for whatever npub account you want. You'd activate the service by sending a Zap (Lightning payment) to get notifications directly to your inbox for that Nostr address.

Not sure if it would be a pay-per-notification or some sort of subscription.

Would this be something useful?
