I'm {{your_role}} at {{your_company}}, chasing unpaid invoices.
Pull my Hunter list {{list_name_or_url}} — contacts with an invoice outstanding.
For each, use the details in {{invoice_number_amount_due_date}} to build the escalation ladder the templates form: a plain due-date reminder, a days-overdue nudge that re-attaches the invoice, an empathetic payment-plan offer where I flag {{payment_plan_ok}}, a work-paused notice, and a final notice naming the contractual consequence.
Front-load the invoice number in every subject for thread-matching, and keep the CTA firm and singular — a closed question asking for a confirmed payment date (this is the one place follow-ups get hard, not soft). Verify addresses, then build it in Hunter for my review.
Grounded in Hunter's invoice templates: name invoice + amount + status → reference/consequence → "Could you confirm a payment date?" Real lines: "I understand that cash flow can be unpredictable.", subject "Invoice [[invoice number]]: final notice before next steps."
Ensure the copy is real, human, and avoids any AI tell-tale signs, including em-dashes, staccato sentences, and unnatural language like: carry, shipped, ask etc.
