Claimify works in four steps: First, you upload a CSV of your overdue invoices — customer names, invoice numbers, amounts, due dates, and contact emails. Claimify parses and normalizes this data instantly. Second, Claimify's AI uses GPT-4 to draft a personalized follow-up email for each customer, calibrated to the invoice amount, days overdue, and your brand voice. Third, you review the drafts and click send — Claimify delivers each email individually from your domain, with proper SPF/DKIM/DMARC authentication. Fourth, Claimify tracks every open, reply, and dispute in real time, classifying each response so you know exactly what action to take next.
