BlackVault Mail. Your Communications. Your Fortress. A glowing red envelope secured with a gold padlock.

Secure business email

Secure, branded email on your own domains.

BlackVault Mail puts every domain, mailbox and team in one protected inbox. Your messages are encrypted at rest, your outgoing mail is authenticated, and your data is never mined.

  • Encrypted at rest
  • SPF, DKIM & DMARC aligned
  • Per-tenant isolation
  • No data mining

Features

Everything your inbox needs. Locked down.

One secure home for every domain you run, with the tools teams use every day.

End-to-End Security

Protection at every stage of a message’s life: encrypted in transit and at rest, with sign-in hardened by passkeys and authenticator codes.

  • In transit
  • At rest
  • At sign-in

Custom Domains

Send and receive as your own domains. Replies always leave from the address the message arrived at, so your brand stays consistent.

Multi-Account & Teams

Run every business from one inbox. Switch domains and mailboxes in a click, and share team inboxes like info@ and support@ with the right people.

Scheduled Send

Write now, deliver when it counts. Queue a message for the right moment and BlackVault Mail sends it on time.

Encrypted Attachments

Files are sealed with the same strong encryption as your messages, and built to work with BlackVault Drive for the big ones.

Secure Backup

Encrypted, off-site backups protect your mail from the failures nobody plans for.

Large Inbox

Room for the long run. Keep years of mail across every domain without ever playing delete-to-make-space.

Security

A fortress around every message.

Security shapes how BlackVault Mail is built, from how mail is stored to how it is sent.

  • Encrypted at rest

    Your messages and attachments are encrypted before they are stored.

  • Authenticated sending

    Outgoing mail is signed and aligned with SPF, DKIM and DMARC for every domain. That helps it reach inboxes and helps protect your domains from spoofing.

  • Per-tenant isolation

    Each organization’s data is kept separate from every other’s and protected with encryption keys of its own.

  • Your own domains

    Bring your domains and your brand. You keep control of your DNS, and mail is always sent as the domain it belongs to.

  • No data mining

    We don’t scan your mail for advertising, build profiles, or sell your data.

How it works

From your domain to your fortress in four steps.

  1. Add your domain

    Tell BlackVault Mail which domains you own.

  2. Verify and connect

    Prove ownership and add a few DNS records. We walk you through SPF, DKIM and DMARC.

  3. Create mailboxes

    Add addresses, invite your team, and sign in with a passkey.

  4. Send and receive

    Work from one secure inbox. Every message goes out as the domain it belongs to.
