Email, without the noise.

Privacy should be the default, not the exception. Xail makes that possible without asking anyone to change how they use email.

Email, without the noise.
About Xail
Boilerplate — for publication

Xail is a secure messaging layer for existing email. It splits every message across independent providers using XorIDA threshold sharing so no single provider ever sees enough data to reconstruct anything. Each share alone is indistinguishable from random noise. Users keep Gmail, Outlook, and Yahoo — no new address, no new app. All encryption happens client-side; Xail's server exists only for OAuth token exchange and never sees message content. Founded in 2026, Xail is available as a free web application at xail.io.

Zero-knowledge
No server ever sees plaintext. Not even ours.
Works with your email
No new address. No migration. Keep your provider.
Spam-free inbox
Only verified contacts appear. Everything else is filtered.
Positioning
What Xail stands for.
Use these themes when describing Xail's mission and values.
Xail stands for
Trust through transparency. Earn trust by eliminating the need for it.
Privacy as a right. A baseline, not a luxury. Free tier includes full security.
Resilience by design. No single point of failure. Distributed systems endure.
Simplicity over sophistication. The complexity is our problem.
The individual over the institution. One person can adopt Xail. No IT department required.
Xail stands against
Surveillance capitalism. Providers read, index, and monetize your email. Xail makes that impossible.
Security theater. If you can't prove it, don't claim it.
Complexity as a moat. PGP exists. Nobody uses it. Hard-to-use security isn't security.
Walled gardens. We don't replace your email. Lock-in is the problem.
Fear-based marketing. We lead with the positive.

Writing About Xail

One-sentence positioning

The only email security that works with your existing providers, requires no keys or passwords, provides mathematically provable privacy, and never asks anyone to change how they use email.

Usage Guidelines
Dos and don'ts.
Use the mark on solid dark or light backgrounds. The V stroke always matches the background color.
Include the period in the tagline: "Email, without the noise."
Minimum reproduction size is 24px wide. Below this the V becomes illegible.
Do not stretch, rotate, recolor, or add effects. The body is always #10B981.
Do not use security tier colors on the mark. Tiers are inbox borders only.
Do not use the Xail name or mark to imply endorsement without permission.
