Essential services for your business.
Built for founders and small teams: bring your own domains, create as many email addresses as you need, and only pay for service usage, not per seat.
K8 HQ is in early access with a small group of design partners. Ask for early access
Projects, not seats
Each project has its own domains, inboxes, people and balance. Launching a side project costs almost nothing.
Works with your mail apps
Standard IMAP and SMTP with app passwords, so Apple Mail, Outlook, Thunderbird and phone mail apps work out of the box.
Encrypted at rest
Every message is encrypted with its own key as it arrives. Spam and malware are rejected before anything is stored.
Pay for what you use
Prepaid credit with clear per-use prices. Unused purchased credit is refundable.
Coming next
- Planned AI rules that label, route and draft replies, with your approval where you want it.
- Planned A zero-access mode for inboxes that even K8 HQ can't read.
- Planned A web app and an API your own AI tools can use.
What K8 HQ is not
K8 HQ is for real people's business correspondence. It is not a bulk or marketing email service, and accounts that send unsolicited mail are paused.
