See what Rillet revenue followed a Constant Contact campaign

**Objective:** For the Constant Contact campaign named `{campaign-name}`, find which clickers are Rillet customers and what was invoiced or contracted for them within `{attribution-days}` days (default 60) of their click.

**Step 1: Identify the campaign**

Call `constant-contact-get-campaign` (constant-contact server) with `name.contains` set to `{campaign-name}`. If several campaigns match, list them with `name`, `campaign-id` and `last-sent-date` and ask which one to use. If none match, say so and stop. Note the campaign's `sends`, `opens` and `clicks`.

**Step 2: Collect the clickers**

Call `constant-contact-get-campaign-click` (constant-contact server) with `campaign-id`. Keep each `email-address` with its earliest click `created-date` and the `link-url` values clicked. If there are no clicks, report the campaign totals and stop.

**Step 3: Match clickers to Rillet customers**

Call `rillet-get-customer-emails` (rillet server) once and match `email` to each clicker's `email-address` exactly, ignoring case and surrounding spaces. Clickers with no match are prospects; count them.

**Step 4: Find what followed**

Call `rillet-get-invoices` (rillet server) and keep invoices for the matched `customer-id` values whose `invoice-date` falls on or after the click date and within the attribution window. Call `rillet-get-contracts` (rillet server) with `customer-id` for each matched customer and keep contracts whose `start-date` falls in the same window.

**Step 5: Report**

* Campaign summary: name, last sent, sends, opens, clicks.
* Clickers: total, matched to Rillet customers, unmatched prospects.
* A table per matched customer: customer, email, click date, links clicked, invoices in window (count and total by currency), new contracts in window (name, start date, total value, currency).
* A closing line with the total invoiced and contracted in the window by currency.

**Rules & Guidelines:**

* Tools starting constant-contact- are on the constant-contact server; tools starting rillet- are on the rillet server.
* State clearly that this is correlation within a time window, not proof the campaign caused the revenue. Existing recurring invoices will appear too; call out customers whose invoice pattern looks unchanged.
* This prompt is read-only. Do not call `constant-contact-resend-campaign-to-non-openers`, `constant-contact-update-campaign` or any other constant-contact-add-* or constant-contact-update-* tool, and do not call any rillet-add-* or rillet-update-* tool.

**Validation:**

* If no clicker matches a Rillet customer, report the prospect count and stop.
* Never add amounts in different currencies.
