End-to-End Encryption

Your Domain, Your Identity
Point any domain to MailVault. Create unlimited addresses under your domain. Full control over your email identity.
Developer First
REST API, Go SDK, and CLI client. Integrate email into your workflow with tools you already know.
How It Works
Up and running in minutes
Add Your Domain
Register your domain and configure DNS records to point to MailVault.
Generate Keys
Use the CLI to generate encryption keys. Your private key stays on your device.
Receive Emails
Emails arrive encrypted at your custom addresses. No one can read them in transit or at rest.
Decrypt and Read
Use the CLI or SDK to decrypt messages. Only you hold the private key.
Built in the Open
MailVault core is open source. Inspect the code, contribute features, or self-host your own instance. Transparency is not optional when it comes to your email.
