Welcome to Vendlen

Vendlen reads an Amazon Ads account, works out what the evidence in it actually supports, and writes that down as a decision you can act on. Decisions you come to trust can then be repeated as Automation, inside criteria and limits you set.

Note

Vendlen was previously named ZonOne. Links to docs.zonone.com open the same page here.

What Vendlen is

Three things, working on the same data:

• AI Analyst reads your listings, targets, search terms and performance history, and writes a Decision Brief: an action, a reason, the evidence behind it, and the scope it applies to.
• Automation repeats operating logic you configured — your criteria, your limits, your Data Window — and shows you every affected target before anything is applied.
• Ads Manager and Campaign Builder are where a decision becomes a change in the account.

What Vendlen is not

It is not an agency service, and it does not run your account for you. Every rule states what has to be true, what it will change, and the boundary it may not cross. Applying a change to a live A rule run produces a preview of every change it would make, and you apply from there.

Where to go first

1. How Vendlen works — the path a decision follows, end to end.
2. Account security — two-step verification, before you connect anything.
3. Connect your Amazon account — the two connections a seller needs.
4. Core concepts — Product Line, Product Group, decision scope, and the Data Window. These four ideas explain most of what you will see in the App.
5. Automation — once you want a decision to repeat without you.
