A separate channel for sensitive conversations.

Plexus is a private mail network for communication between Plexus users. It does not send to or receive from conventional email. Encrypted packages travel between registered devices while readable conversations stay with their participants.

01

Create your Plexus identity

Choose a public handle and secure access with a passkey protected by your device, security key, or password manager.

02

Connect with Plexus users

Exchange mail inside the Plexus network. Messages do not pass through Gmail, Outlook, or other conventional email services.

03

Keep readable mail local

Every delivery is encrypted for each recipient device. Readable mail and private messaging keys remain in the local vault.

What the service sees—and what it doesn't.

Stored by Plexus

Public handles and device keys, authentication records, routing information, encrypted relay packages, and delivery state.

Kept on your device

Readable messages, contacts, drafts, mailbox history, and private messaging keys in your encrypted local vault.

Shared only by your choice

If you deliberately file a safety report, the reported excerpt and context are shared for review.
