# Send shoppers to Iterable

> Shopper ID with Iterable: what's charged, what's supported, and how to connect it.

Category: Destinations

Included on the **Growth** plan and above.

## What you're charged
Before we charge, we check whether the shopper is already in your Iterable. New shoppers cost 2 credits, once; shoppers already there cost 1 credit, are never duplicated, and get a **WhoLayer Returning Shopper** event instead.

## What Iterable supports
- **Checks your list first:** yes.
- **Refunds bounces:** yes, bounces and spam complaints within 30 days.
- **Deliverability Guard:** a fixed cap of 50 new contacts a day (or your own setting, if lower), because we can't read your rates.
- **Holdout report:** yes, from your orders.

## Connect it
1. In Iterable, open **Integrations → API keys** and create a **Server-side** key in the project your store uses.
2. In WhoLayer, open **Destinations**, choose **Iterable**, paste the key, and pick the data center (US or EU) your project is in.
3. Click **Send test**, then look for the user "avery.sample@example.com".
4. Build a journey triggered by the **WhoLayer Shopper Identified** or **WhoLayer Returning Shopper** custom event. Iterable adds new users in the background, so in some projects the very first event can arrive before the user exists; the user also gets a `wl_shopper_identified_at` field you can trigger on as a backup.

## Good to know
- Iterable has no account-wide 7-day bounce and complaint counts, so the Deliverability Guard uses a fixed daily cap.
- Opted-out people are never sent, and opt-outs take effect immediately.
- We encrypt your key when you save it and only ever show its last characters.
