Standard System Automation
Subject: System Notification: Overdue Invoice #123

This is an automated notification. Your payment for Invoice #123 is now overdue. Please settle this immediately to avoid further action.

Generic system emails land in spam, get ignored, and signal a cold, transactional relationship.

RemindGently Approach
Subject: Quick note on [Project] invoice

Hi [Name], hope everything is going great! I'm sending a quick note as our system hasn't flagged Invoice #123 as paid yet. Knowing you, it's just a small oversight...
