The problem
Opted out in Mailchimp, still mailed from HubSpot
Someone who unsubscribes from a Mailchimp campaign can still be subscribed in HubSpot and keep getting its marketing email. Catching up means exporting unsubscribes, checking who rejoined and finding each person in HubSpot by hand.
Without PopdockAI
- Export recent campaign unsubscribes from Mailchimp
- Check whether each person rejoined the audience
- Search HubSpot one contact at a time
- Change subscriptions by hand and hope none were missed
With PopdockAI
- Recent campaign unsubscribes are read, latest per email
- People who rejoined the audience are left out
- HubSpot status is checked by email for the type you name
- Nothing changes until you confirm, and a sample is rechecked

**Objective:** Unsubscribe from the HubSpot subscription type `{subscription-name}` the people who have unsubscribed in Mailchimp in the last `{lookback-days}` days (default 30), after the user confirms, so HubSpot stops sending marketing email to people who opted out in Mailchimp.
**Step 1: Resolve the HubSpot subscription type**
Call `hubspot-get-subscriptions` with `name.contains` set to `{subscription-name}` and `active` set to true. Exactly one must match. If none or several match, list them (name, purpose, communication-method) and stop. Keep its `subscription-type-id` and `name`.
**Step 2: Unsubscribed people in Mailchimp**
Call `mailchimp-get-campaign-unsubscribe` with `unsubscribe-date.from` set to today minus `{lookback-days}` days (30 if blank). Keep `email`, `first-name`, `last-name`, `unsubscribe-date`, `reason`, `campaign-name` and `list-id`. If an email appears more than once, keep the most recent row. This covers unsubscribes from campaigns only; say so in the report.
**Step 3: Check each person in HubSpot**
For each distinct email address:
* Call `mailchimp-get-list-member` with `email` set to the email. If the member is now subscribed again in the same audience (`list-id`) they unsubscribed from, put them in "resubscribed in Mailchimp since" and leave them out.
* Call `hubspot-get-contact-subscriptions` with `recipient-email` set to the email. Find the row whose `subscription-id` equals the `subscription-type-id` from Step 1. If its `status` is not subscribed (NOT_SUBSCRIBED or equivalent), put the person in "already unsubscribed in HubSpot". If it is subscribed, or its value is unclear, put them in "will unsubscribe" and keep the raw status.
* If no row for that subscription comes back, call `hubspot-get-contacts` with `email` set to the email. If no contact comes back, put the person in "not in HubSpot". If a contact comes back, put them in "will unsubscribe" with HubSpot status "no record".
**Step 4: Confirm**
Show the subscription type name and id, then the groups: will unsubscribe (email, name, Mailchimp unsubscribe date or status, HubSpot current status), already unsubscribed in HubSpot (count), resubscribed in Mailchimp since (list), not in HubSpot (list). Ask the user to confirm the "will unsubscribe" group, or to name people to leave out. Do nothing more until they confirm.
**Step 5: Unsubscribe in HubSpot**
Only after confirmation, call `hubspot-unsubscribe-contact` once per confirmed person, with `email` set to their email and `subscription-id` set to the `subscription-type-id`. Do not send `legal-basis` unless a call fails asking for one; then stop, tell the user GDPR is on for the portal, and ask which legal basis to use before continuing.
**Step 6: Verify and report**
Call `hubspot-get-contact-subscriptions` again for up to 5 of the people you changed and show their new status (HubSpot can take a minute to update). Then the totals: unsubscribed, failed (with the error), already unsubscribed, resubscribed in Mailchimp since, not in HubSpot.
**Rules & Guidelines:**
* `mailchimp-get-campaign-unsubscribe` and `mailchimp-get-list-member` are on the Mailchimp server; `hubspot-get-subscriptions`, `hubspot-get-contact-subscriptions`, `hubspot-get-contacts` and `hubspot-unsubscribe-contact` are on the hubspot server.
* `hubspot-unsubscribe-contact` is the only write tool this prompt may call, once per confirmed person, after Step 4. Do NOT call `hubspot-subscribe-contact`, and call no other hubspot-add, hubspot-update, hubspot-rename, hubspot-remove, hubspot-subscribe, hubspot-unsubscribe or hubspot-import tool.
* Mailchimp is read-only here. Do NOT call `mailchimp-add-list-member`, `mailchimp-update-list-member`, `mailchimp-add-customer`, `mailchimp-update-customer`, `mailchimp-add-segment-member`, `mailchimp-start-automation`, `mailchimp-pause-automation`, `mailchimp-replicate-campaign`, `mailchimp-update-product` or `mailchimp-update-order`.
* This prompt only ever removes consent. Never subscribe or resubscribe anyone in either system.
* Match on email address only, compared case-insensitively with surrounding spaces trimmed. Never match on name alone.
**Validation:**
* If Mailchimp returns no unsubscribed people, say so and stop.
* If everyone is already unsubscribed in HubSpot, resubscribed since, or not in HubSpot, report the counts and stop without asking for confirmation.
* If one unsubscribe call fails, report it with the error and continue with the rest.Who it's for
