The problem
Opted out in Mailchimp, still on the store list
People who unsubscribe in Mailchimp can stay on the BigCommerce newsletter list, which risks compliance complaints. Spotting them means exporting unsubscribes and searching the store subscriber list address by address.
Without PopdockAI
- Export recent unsubscribes from Mailchimp
- Search the BigCommerce subscriber list for each
- Note dates and reasons in a spreadsheet
- Hope nobody complains first
With PopdockAI
- Recent unsubscribes are read, optionally for one campaign
- Up to 50 distinct emails are checked in BigCommerce
- Still subscribed people come back with date, reason and ID
- It only reads and leaves removal to the store owner
The prompt

**Objective:** Find people who unsubscribed through Mailchimp in the last `{lookback-days}` days (default 30) but still appear as newsletter subscribers in BigCommerce. Limit to the campaign `{campaign-id}` when it is given.
**Step 1: Read the Mailchimp unsubscribes**
Call `mailchimp-get-campaign-unsubscribe` (mailchimp server) with `unsubscribe-date.from` set to the start of the window, and `campaign-id` set to `{campaign-id}` when it is not empty. Keep `email`, `unsubscribe-date`, `reason` and `campaign-name`.
**Step 2: Look each one up in BigCommerce**
For each distinct email (at most 50), call `bigcommerce-get-subscriber` (bigcommerce server) with `email` set to the address. Keep `id`, `source` and `date-created` when a subscriber record exists.
**Step 3: Report**
List the people who unsubscribed in Mailchimp and still have a BigCommerce subscriber record, with `email`, `unsubscribe-date`, `reason`, and the BigCommerce subscriber `id`. Give counts of unsubscribes checked, still subscribed in BigCommerce, and not in BigCommerce. Say that removing them is a separate decision for the BigCommerce owner.
**Rules & Guidelines:**
* `mailchimp-*` tools run on the mailchimp server and `bigcommerce-*` tools on the bigcommerce server. Both servers must be connected.
* This prompt is read-only. Never call `bigcommerce-subscriber-delete`, `bigcommerce-subscriber-update` or any other `bigcommerce-*-add`, `-update` or `-delete` tool, and never call any Mailchimp write tool.
**Validation:**
* If Mailchimp returns no unsubscribes, say so and stop.
* If more than 50 distinct emails were returned, say only the first 50 were checked.
