Nitro documentation
Nitro adds six tools on top of Blueshift’s Email Studio. Each guide below covers the problem the feature solves, how it works under the hood, and how to use it day to day.
Every feature has its own on/off switch in the Nitro popup (click the Nitro icon in Chrome’s toolbar). Changes apply instantly, with no page reload needed.
Gmail Clipping Guard
A live size meter that warns before your email crosses Gmail's ~102 KB clip point, with per-row weight analysis to find what's heavy.
