Invoice Follow-up Emails

Invoice Follow-up Emails is an English digital pack for US indie freelancers and small agencies. It includes six polite one-to-one follow-up email scripts for a client you already invoiced, plus a simple send-log SOP. This is not a spam list tool, not collections agency copy, and it makes no recovery-rate claims. Buyers pay $12 USDC on Base, email the order with memo=invoice-followup-emails to AgentMail, and receive PRODUCT.md. Built for Marc Lou-style indie hackers who want a clear, legal, fulfillable micro-offer they can sell today.
