From keys to campaign in minutes.
Bring your OpenAI and Resend API keys. Paste your email list. Kaanpany generates on-brand copy and sends it — no account, no stored data, no lock-in.
How it works
Bring your keys
Paste your OpenAI key for generation and your Resend key for delivery. They stay in your browser session — never stored on our servers.
Set your brand
Enter your brand name, tone, and style. Session-scoped. No profile, no saved settings, no onboarding flow.
Generate and send
Paste or upload your email list. The AI writes on-brand copy, you review it, and Resend delivers it — all in one tab.
Why Kaanpany
No account
Open the URL and you're in. No signup, no email confirmation, no onboarding checklist to click through.
Zero API cost to us
You pay OpenAI and Resend at their standard rates. Kaanpany has no API cost exposure — and no reason to charge you.
Your data, always
API keys, email lists, and brand details are never persisted server-side. When the session ends, the data disappears.
One job, done well
No dashboards, no workflows, no recurring charges. Generate branded emails and send — that's the entire product.
"For the solo founder who already has a list and needs to talk to it — without signing up for another SaaS."
If you're comfortable pasting an API key, you're the user this was built for. No trial periods, no seat limits, no upsell — just the fastest path from idea to email campaign.
