Who we are, and why Norbelys exists

Hi there,

We built Norbelys because cold email got loud.

Most tools help you send more. We wanted one that helps you get answered. We’re Xuxil, Inc., a software company incorporated in Delaware, and Norbelys is what we make.

Here’s what we believe, and where you’ll find it in the product.

Replies are the point. A campaign isn’t done when it sends. It’s done when someone writes back. So follow-ups stop the moment a person answers, every reply lands in one inbox and the ones that matter rise to the top.

In the product: Stop on replyOn

Slower is faster. Every inbox sends at a human pace: 50 emails a day, ten minutes apart, unless you choose otherwise. Your domain stays healthy, and you’re still sending next quarter.

In the product: Each inbox sends50 a day, 10 minutes apart

Your mailboxes, your data. Norbelys sends from the inboxes you already own. Your contacts and your replies stay yours: export them whenever you like, and if you leave, everything is erased 30 days later.

In the product: Exportpeople.csv, history.jsonl

AI that only says what’s true. It writes first lines from facts you approve and sends your own words when it has nothing true to say. It never sees the address of the person it writes to, and nobody trains a model on your data.

In the product: AI first linesOnly from facts you approve

One price, everything in it. AI, warm-up, tracking, the inbox and the API are all in the plan. No credits, no add-ons, no surprise invoice.

In the product: Plan$20 a month, all in

When you write to us, a person who works on Norbelys reads it and writes back.

Thanks for reading this far. That’s more than most cold emails get.
