A one-off payment of £199 for a lifetime licence.
Every 1.x update included.
Try KT8 Mail for 14 days. When you’re ready, a single lifetime licence covers your entire organisation and all 1.x updates, with no per-user or per-mailbox fees. Sending email needs Cloudflare’s Workers Paid plan (approx. $5/month), paid directly to Cloudflare.
Fair ownership, with no lock-in
Your data is never locked away. If you decide not to buy after your 14-day trial, emails keep arriving and you can read or export all of them whenever you like.
A true lifetime licence. Your own copy of KT8 Mail checks its licence key itself, without contacting our servers, so it keeps working even if KT8 closes.
No forced upgrades. Use the version you bought for as long as you like. Features you’ve paid for will never expire or move behind a paywall.
A full year of domain monitoring, free
Install KT8 Mail during our launch and we’ll monitor your domain at no charge.
- Uptime checks: we check your KT8 Mail is responding every 5 minutes, day and night.
- DNS and blocklist checks: your email records and well-known blocklists are checked every 6 hours.
- Expiry reminders: an email before your domain or its SSL certificate expires.
- DMARC reports: see who sends email as your domain, from your own services to fakes.
It’s included during your 14-day trial and for 12 months after you buy a lifetime licence. After a year it simply ends, with no hidden charges, no auto-renewal and nothing to cancel. You can switch it off at any time in your KT8 account.
KT8 Mail runs on Cloudflare, so changes Cloudflare makes to its own services are outside our control. KT8 Mail is built on Agentic Inbox, which Cloudflare has published as open source.
Your own email. No servers to manage.
