Answer

It takes the first line, so you don't hire for it.

Shoppers ask before they buy. The agent answers from your catalogue in seconds, in any language, acts in your own systems through connectors, and asks your team in Slack when it doesn't know. Every answer your team gives is saved as an article, so nobody gets asked twice.

Also written from the same brief: Lithuanian, German, and the SMS. The variant that converts best goes to the rest of the segment.

Variants that competeSeveral versions go out, and the one that reaches the goal or gets replies is sent more.
A holdout groupPart of the segment is set aside and never mailed, so the campaign is told apart from orders that came anyway.
GuardrailsDaily, budget and per-contact caps, quiet hours in the contact's timezone, and a pause when bounces climb.

Know

Run it from Claude or ChatGPT. Ask your shop anything.

Every screen in Zellwo is also a tool for your own AI assistant over MCP. Ask about your business, get the number. Describe a campaign, get it built. The CEO's analyst, in Claude or ChatGPT. It acts with the same permissions as the person who connected it.

> Who searched winter tyres this week and didn't buy?212 people, 148 with an email.> Make a campaign for them, 10% control group.Drafted three variants. Sends start at 09:00 in their timezone.

Plain languageAsk the way you would ask a colleague, with no reports to build and no filters to learn.
Your own dataEvery answer comes from your tickets, contacts, events and campaigns, not from the web.
Drafts the next actionAn answer ends in a draft, the article, the campaign or the follow-up, waiting for your yes.

For developers

Every screen is an endpoint. Built for developers too.

A REST API with every screen as an endpoint, an event feed in and out, a JavaScript SDK, and an MCP server so your own agent can run it. Send a purchase from your own system and the contact moves to Active customer, its win-back campaigns stop, and the agent sees the order.
