Dry-run before Live: how Sheet Engine treats Gmail
A mature-product note on why Sheet Engine refuses silent historical backfill and how the 15-day trial relates to Live.
Gmail daily limits are real. A watched column that fires on every edit is also real. Sheet Engine therefore makes dry-run the primary control.
During the 15-day trial you can enable Live and learn the log. After the trial, gallery and dry-run stay; sends wait on a $5/mo, $55/year, or $250 lifetime subscription.
Emails come from your account. There is no open-tracking pixel in v1. Quota copy links Google’s published limits — we do not invent a second meter.
