About Gemma for Emarsys

Chrome extension for the Emarsys email builder: mobile preview, text highlighting, custom color swatches, condensed blocks panel, and an in-app settings panel with a nav entry.Gemma for Emarsys is a Chrome extension that enhances the Emarsys email editor with productivity tools, UI improvements, and quality-of-life features designed for marketers who build emails every day. If you work in Emarsys regularly, Gemma helps you create emails faster, reduce errors, and stay focused by improving the parts of the editor that slow you down. 🚀 Faster Email Creation Create and manage reusable ESL snippets and drag them directly into the email editor. Snippets can be edited, pinned, categorized, deleted, and shared using import/exportable JSON files. Perfect for personalization logic and repeatable content. 🎨 Clearer Editing & Visual Feedback Important text in the editor preview can be automatically highlighted so dynamic content is easy to spot while editing. Highlight rules and colors are fully customizable in the settings panel. 📱 Built-in Mobile Preview View a live mobile preview next to your desktop layout while editing emails. The preview can be toggled on or off, resized by dragging, and scaled from the settings panel. A mobile preview is also shown when loading contact previews. 🖌️ Persistent Color Swatches Custom color swatches are saved permanently so your brand colors are always available. You can also define up to eight default color presets that stay pinned to the top of the color picker. 🧱 Smarter Blocks Panel Choose how many content blocks appear per row to reduce scrolling. Pin frequently used blocks to the top and hide blocks you never use. All preferences persist across sessions. 🖼️ Easier Image Editing When adding images, see a live preview next to the image editor. This makes writing accurate ALT text faster and less error-prone. 🖥️ Fullscreen Email Editing Expand the email editor to fullscreen to gain over 40 percent more visible workspace. Ideal for complex layouts and long emails. ⌨️ Keyboard Shortcuts Save drafts instantly using CMD+S or CTRL+S. Toggle the mobile preview using CMD+/ or CTRL+/. Fewer clicks, faster workflows. 🚨 Unsaved Draft Warnings If your email has unsaved changes, an animated indicator appears in the browser tab so you don’t forget to save your work. 🧠 Helpful Browser Tab Titles Browser tabs are renamed to show the current email campaign name, making it easy to work with multiple emails at once. ⚙️ Additional Improvements Instantly convert plain text ESL into ESL tokens by clicking the convert icon in the content block toolbar. Customize the content block toolbar Toggle columns in the media directory Automatically focus the link editor input Auto-expand long preheader text fields Copy campaign names to the clipboard with one click Gemma does not replace Emarsys. It enhances it. If Emarsys is part of your daily workflow, Gemma helps you work faster, make fewer mistakes, and enjoy using the platform more.
