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.
If a guide doesn’t answer your question, or something isn’t working the way it’s described, head to support and feedback.
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.

Unsaved Changes
Dirty-state tracking for Email Studio: tab dots, a status pill next to Save, and browser-tab markers so you know what's safe to close.

Shared Asset Configurator
Turn a shared asset into a configurable module with a JSON schema. Nitro renders the form, previews live, and writes the block back.

Vertical Rhythm
Normalize top and bottom padding across rows, columns, and blocks to a ruleset, with a dry-run diff before anything changes.

Preview how real clients recolor your email in dark mode, catch the color combos that break, and auto-fix them, using measured client models.

Beyond Nitro
Nitro is a side effect of years spent shipping email programs on Blueshift. If your team needs help with strategy, templates, or integrations, that’s what Studio 625 does all day. Start a conversation.
