Business email today is a jigsaw

A different provider for every mailbox, PEC managed on the side, shared accounts you can’t govern and no link to the files and calendar you work in every day.

Without kMail

  • Different providers and webmails for each domain and mailbox
  • PEC and certified mailboxes handled in a separate tool
  • Attachments downloaded by hand, no link to files or calendar

With kMail

  • Every mailbox and domain in one branded webmail
  • PEC and external accounts next to ordinary mail
  • Attachments to Files and calendar events in one click

All your business email in one webmail, with AI inside

kMail manages your company’s email in one webmail: mailboxes on your domain or connected from external providers via IMAP/SMTP, with a modern webmail, a rich editor, scheduled send, snooze and follow-ups. And it brings AI into the mailbox, to help you write and keep the inbox tidy. Self-hosted on a JMAP backend, on servers in Europe, integrated with the rest of the Kamzan ecosystem.

Your domain, verified in minutes

Add your domain and kMail generates the DKIM keys and walks you through DNS setup with copy-paste instructions. MX, SPF, DKIM and DMARC verified in real time: emails leave authenticated and actually arrive.

Shared mailboxes and aliases info@, support@ with members and send permissions, plus aliases and multiple HTML signatures.

Write now, let it leave at the right moment

Undo send, delayed send and scheduled send for the right hours. kMail nudges you if a recipient hasn’t replied yet and lets you snooze an email so it comes back when you need it.

Automatic follow-ups Reminders at 3, 7 or 14 days if no reply arrives, without leaving your inbox.

Private AI

kMail that writes and sorts itself with you

kMail brings AI into the mailbox on two fronts: it helps you write — rewriting a draft in the right tone, from formal to concise — and it triages the inbox, classifying every message by category and priority, with a summary and the action items. Models are your choice — Claude, GPT, DeepSeek or a local self-hosted model — and everything is opt-in.

  • Rewriting in the right tone Turn a draft into formal, professional, concise or cordial: eight tones, with a preview before you apply.
  • Automatic email triage kMail triages your email automatically: every message is classified by category — urgent, needs reply, newsletter — and sorted by priority and importance.
  • Models of your choice, self-hosted too Claude, GPT or DeepSeek, or a local self-hosted model on Kamzan infrastructure. Always opt-in.
All your business email in one webmail: mailboxes on your domain and external accounts connected via IMAP and SMTP, without changing your addresses.

Email that talks to the whole ecosystem

Save an attachment to Kamzan Files or attach a file without downloading it, create a calendar event straight from an email, complete recipients from the Kontacts address book. One login for email and every other tool in the Kamzan ecosystem.

Your email, under your control

kMail isn’t just convenient: it’s built for companies that can’t compromise on their data.

  • Your data stays yours kMail lives on Kamzan’s own infrastructure, not in an external service you know nothing about. No profiling, no ads.
  • AI on-premise too Use cloud AI models or self-hosted models on Kamzan infrastructure: emails never go out to external AI services. Ideal for private healthcare, finance and anyone handling sensitive data.
  • Built-in protection Anti-spam filtering, DKIM, SPF and DMARC set up with guided DNS verification: your emails actually arrive and don’t land in other people’s spam.
  • PEC and certified mail Manage PEC certified mailboxes alongside ordinary ones, all in one interface.
  • Secure access Single sign-on across the Kamzan ecosystem (SSO/OIDC) and dedicated app passwords for external clients, separate from the account password.
  • Compliant and traceable Per-folder retention rules and a privacy-first approach consistent with the whole Kamzan ecosystem (GDPR).

Built for those who can’t take risks with email

kMail is the natural choice when confidentiality, continuity and control really matter.
