Every week, someone at an ad agency writes this email to a client by hand.

I built a tool that writes it in 10 seconds, and checks every number so a wrong one never reaches the client.

1 It writes the email a client gets.

Each run writes new sentences. Every number comes from the spreadsheet, worked out by code, not the AI.

2 It works from the ad spreadsheet.

AudienceSign-ups, last week → this week

Sample numbers for a made-up school, so no real client data is shown.

3 It checks every number.

Each number in the email has to match the spreadsheet math for the audience it talks about, and "rose" or "fell" has to match which way it moved.
