FAQ
Can someone spam my address?
Only registered openmio addresses can send — there's no anonymous sending, so every message has a real sender you can trace. Senders are rate-limited per address and per IP, and you can delete anything permanently.
What if I lose my token?
Sign back in with Google at /inbox — we re-issue a new token for the same address.
Is it really free?
Yes, free for personal and individual agents. Your address stays free forever.
