The problem
Moving HubSpot lists into Mailchimp can bring back people who left
Getting a HubSpot list into a Mailchimp audience usually means an export, a spreadsheet comparison and an import. It is easy to add people who already unsubscribed or to resubscribe someone Mailchimp cleaned.
Without PopdockAI
- Export the HubSpot list to a spreadsheet
- Compare emails against the Mailchimp audience
- Check opt-outs one contact at a time
- Import and risk resubscribing cleaned addresses
With PopdockAI
- Members are matched by email to find who is missing
- HubSpot opt-outs are skipped and listed with the reason
- Existing audience members are left alone, whatever their status
- New people are added as pending so Mailchimp asks them to opt in

**Objective:** Find the members of the HubSpot list `{hubspot-list-name}` who are not in the Mailchimp audience `{audience-name}` and, only after the user confirms, add them to the audience with status `pending`.
**Step 1: Resolve both lists**
* Call `hubspot-get-contact-list-membership` with `list-name` set to `{hubspot-list-name}`. Note `contact-id`, `contact-email` and `contact-first-name`. If nothing comes back, say the HubSpot list is empty or not found and stop.
* Call `mailchimp-get-list` with `name` set to `{audience-name}`. If exactly one audience comes back, note its `list-id`. If none or several come back, list what was found and stop.
**Step 2: Compare by email**
For each HubSpot member with an email:
* Call `mailchimp-get-list-member` with `email` set to it and `list-name` set to `{audience-name}`. If any row comes back, whatever its status, the person is already in the audience. Leave them alone.
* For a person not in the audience, call `hubspot-get-contact-subscriptions` with `recipient-email` set to their email. If any subscription has a status that is not subscribed (for example unsubscribed or opted out), put them under "Skipped, opted out in HubSpot" and do not add them.
Call `hubspot-get-contacts` with `record-id` set to the `contact-id` only when you need a last name for someone you are about to add.
**Step 3: Confirm**
Show three lists: Already in audience (count only), Skipped (email and reason), To add (name and email). Ask the user to confirm the To add list. Do nothing further until they say yes. If they remove people, drop those people.
**Step 4: Add the confirmed people**
For each confirmed person, call `mailchimp-add-list-member` once with `list-id` from Step 1, `email-address`, `first-name`, `last-name` and `status` set to `pending`. Never use `subscribed`: `pending` sends Mailchimp's opt-in confirmation email.
**Step 5: Report**
How many were added, how many failed and why, and the skipped list.
**Rules & Guidelines:**
* `hubspot-get-contact-list-membership`, `hubspot-get-contact-subscriptions` and `hubspot-get-contacts` are on the HubSpot server; `mailchimp-get-list`, `mailchimp-get-list-member` and `mailchimp-add-list-member` are on the Mailchimp server.
* Match on email address only, compared case-insensitively with surrounding spaces trimmed. Never match on name alone.
* The only write allowed is `mailchimp-add-list-member`, once per confirmed person, after Step 3. Do not call `mailchimp-update-list-member`: never re-subscribe someone who unsubscribed or was cleaned.
* Do not call `hubspot-add-contact`, `hubspot-update-contact`, `hubspot-add-contact-note`, `hubspot-add-company`, `hubspot-update-company`, `hubspot-add-company-note`, `hubspot-add-deal`, `hubspot-update-deal`, `hubspot-add-deal-note`, `hubspot-add-ticket`, `hubspot-update-ticket` or `hubspot-add-ticket-note`. HubSpot is read-only in this prompt.
**Validation:**
* Skip HubSpot members with no email and count them in the report.
* If `mailchimp-add-list-member` fails because the person is already a member, count them as already in the audience, not as a failure.Who it's for
