How it works

Three steps, all in your inbox

01

Put us in the bcc

Email your client like you always do, with Klantr in the bcc. That's how we know when you last had contact — we never read your inbox.

02

The clock runs on your real email

The clock runs on your real email, not on what you do inside Klantr. No false alarms, so you keep trusting the warnings.

03

Reply with one line

When a client goes too quiet, we email you. Reply with one line and Klantr writes and sends the update. You never open a dashboard.

Maker · Klantr

I'm Cemal, the maker of Klantr. I built it because I kept seeing the same thing at the solo agencies around me: the monthly update that never gets sent, and the retainer client who quietly drifts off before anyone notices.

Klantr does exactly those two things — and nothing else. You type one line, it writes a client-ready update in your own tone, and it flags any client who's gone quiet too long. No suite full of buttons, no noise.

I build it, maintain it, and answer every email myself. If something isn't working the way it should, you hear it straight from me — not from a ticketing system.
