Nitro for Blueshift

Helpers for Blueshift’s Email Studio: spend less time on tedious QA, and ship with confidence.

Nitro adds six tools to Blueshift's Email Studio, so you can move faster and spend less time on tedious QA. It runs entirely inside your browser, on Blueshift pages only. No signup, no account, no servers. FEATURES: Gmail clipping guard Gmail cuts off emails larger than about 102 KB and hides the rest behind a "View entire message" link. Nitro shows a live HTML size meter next to the editor tabs, colored green, yellow, or red against that threshold. Switch on inspect mode to label every row with its own size and find the heavy block in seconds. The meter works in Journey Builder too, so oversized templates don't slip through. Dark mode preview See how email clients invert your colors before you send a test. Preview the template as Gmail on Android, as Outlook, or under a full inversion. Nitro flags text and background pairs whose contrast breaks, catching invisible buttons and vanishing logos, and can rebalance the colors for you. Preview the fix before you keep it. Shared asset configurator Configure shared assets with a form instead of hand-editing Liquid. Every parameter gets a proper control, merge tags resolve live, and the preview updates as you type. When it looks right, write the block straight back into your template. Vertical rhythm Normalize padding across rows, columns, and blocks in one pass, with per-block-type overrides for the elements that need different treatment. Preview the change before you apply it. Liquid highlighting Colorize Liquid tags, output, and [shared_asset] blocks on the canvas, so template code is readable at a glance. Unsaved changes indicator An "Unsaved changes" or "No changes" pill next to Save, plus a marker on whichever tabs hold edits, so you know if a save is needed before you close. PRIVACY Nitro has no servers of its own, includes no analytics or tracking, and sends nothing to the developer or to any third party. Your preferences are kept in Chrome's own storage. Email content, templates, and account data are never collected or transmitted. REQUIREMENTS A Blueshift account. Nitro activates on app.getblueshift.com and does nothing on any other site.
