About
Aster Mail is a free, open-source, end-to-end encrypted email service for people who want real privacy without the technical overhead. All encryption happens on your device before anything reaches our servers, so we have zero access to your messages or metadata.
Aster uses standard OpenPGP with portable RSA-4096 keys, so you're never locked in. Your keys work with GPG, Thunderbird, or any PGP client, and they're discoverable through WKD and public keyservers. Aster-to-Aster messages use a Signal-inspired X3DH and Double Ratchet protocol for forward secrecy.
Every plan includes encrypted email, custom domain support, free aliases, tracker protection, and full access across web and desktop. The entire codebase is published under AGPL v3 on GitHub, fully auditable, with a public warrant canary and documented vulnerability disclosure.
Free plan includes 10 GB encrypted storage, 5 aliases, and 1 custom domain. Paid plans start at $2.99/month. Servers located in Germany.

About
Deepbluework is a hosted business email and collaboration service for teams using a domain they already own. It provides custom-domain mailboxes with IMAP/SMTP access and 10 GB of storage per mailbox. Users can manage calendars, invitations, reminders, and browser-based video meetings, and create encrypted notes that can be shared through password-protected links. Administrators can add, suspend, and organize users, create distribution groups, view an organization chart, and manage domain settings and billing in a web dashboard. DomainConnect can automate DNS setup at compatible registrars; other domains can be configured with provided records. The service also supports forwarding selected mail to Chato.pro and access through standard IMAP/SMTP email clients. Deepbluework offers web, iOS, and Android access for businesses and small teams seeking email and related communication tools on a custom domain.
