Dry-run and Live

Stub: dry-run lists rows and mail fields without sending. Live and Run once respect the 15-day trial and subscription.

Dry-run never sends. It shows a sample of matching rows and the composed subject/body.

Enable Live or Run once only after the sample is correct. After the trial, those controls require a subscription; recipes stay saved.

Failures write to SheetEngine_Log. Add-on triggers do not email Google’s failure notice — the log is the product.
