Everything you need to know about stealth sending, identity protection, and why the other guys are just "Hot Air".

Common Questions

Why does G*mail show my address in brackets?

Because they want to make sure the recipient knows you're a "spoofing" risk. It's their way of keeping you in their walled garden. If you don't verify your alias carefully, they'll leak your primary identity every time.

What is a "Master Relay" (V6)?

It's our proprietary invention. We use a verified "Bridge" address to carry your message. We use the Golden Mask trick to show your temp address as the sender's display name while the verified bridge handles the technical handshake. No brackets. No disclosure. Just pure privacy.

Is this safe for my main account?

100%. We use official Google OAuth and API protocols. We never see your password, and we only send what you tell us to. Think of us as a professional courier service for your digital mail.
