Use case
Citizen Engagement
Replace postal letters with LetroLetter: official notices delivered to verified citizens, with proof of sending and receipt, on infrastructure the public body controls.
What it is
A channel for public bodies to deliver official notices to verified citizens with proof of sending and receipt, running on sovereign infrastructure the public body controls — including fully self-hosted or air-gapped deployments.
Why public communication belongs in Letro
Official notices, delivered digitally
LetroLetter delivers notices to a citizen's verified device instantly, with proof of sending and receipt designed around eIDAS 2.0 requirements.
Sovereign by design
Run Letro on your own infrastructure in your jurisdiction — private server or air-gapped — so the public body stays in control of citizen data.
Accessible without a portal
Citizens use a phone app with a verified PostNumber. No accounts to recover, no portal to learn.
Identity-bound access
Personal data is exposed only to the verified recipient; nothing is broadcast to a global inbox.
How citizen engagement works in Letro
From notice to acknowledged receipt, with the record kept by you.
01
Verify the citizen
Citizens register once with their passport and address to receive a PostNumber.
02
Send the notice
Compose a LetroLetter from a template and send to the verified PostNumber.
03
Record receipt
Delivery and opening are timestamped in the audit chain you operate.
04
Respond and resolve
Citizens reply in the same secure channel, improving response times and engagement.
Discuss Your Deployment Model
Whether you need a standard rollout, private infrastructure, or stricter residency and isolation requirements, Letro gives you a trustless foundation for secure client communication.
