Our mission

Communication tools should multiply your team's output, not your software bills.

When we started Kadyan Industries in 2023, we were paying ₹2 lakh a year across five SaaS subscriptions just to handle email, marketing, tasks, and automation. Five logins, five invoices, five APIs that didn't talk to each other. We knew there had to be a better way.

So we built one. RabiMail is what we wish had existed when we needed it: a single coherent platform that does email and marketing and Kanban and automation — properly, not as bolt-ons. Built in India, for businesses everywhere, with sovereign hosting for those who need it.

What we believe

Six principles we don't compromise on.

Customers own their data

Always. No selling, no training models on it, no fine-print exceptions. If you leave, you take everything with you.

Pricing should be honest

Flat per-mailbox fees. No "starter" plans that hide critical features. No per-email or per-contact gotchas.

India-first, not India-only

We build for Indian regulations, Indian languages, Indian payment systems — and then ship that quality globally.

Sovereignty is non-negotiable

For regulated industries, self-hosting isn't a "nice-to-have." We engineer for it from day one.

Less is more

One coherent product beats 30 stitched-together apps. We resist the urge to add features that don't earn their place.

Support is a product feature

Real humans, fast response, no chatbots-as-gatekeepers. If you need us, we're there.
