Private by design.
A privacy-first email workflow focused on reducing spam exposure and keeping your inbox clean, organized, and protected every day.


Transport encryption (TLS) is used, where supported, to help protect messages while they move between mail servers.

No profiling. No ad tracking. No marketing analytics. Information stays limited, purpose-bound, and under your control.

Guided by minimal collection, sensible defaults, and clear boundaries. Focused on practical, defensible privacy choices.

Exploring methods to compartmentalize exposure and reduce unwanted mail across real-world scenarios.

Owner-operated and periodically reviewed to support reliability and strong security hygiene.

Use your existing inbox on web, mobile, or desktop. Nothing new to learn, just more control over your mail.
Use a custom domain to maintain a consistent identity while exploring privacy-forward email routing patterns behind the scenes. No sign-ups: @hcnmail.com is reserved for the project administrator.


Works with Thunderbird, Outlook, Gmail, Apple Mail, and most webmail providers, allowing you to keep using the tools you already know and trust.
