Gmail and Microsoft Outlook serve different purposes, but many users miss Outlook's robust features and familiar interface when sticking with Gmail. The good news? You can bridge that gap with Chrome extensions that enhance Gmail's functionality and appearance.
Whether you're configuring Gmail for desktop-like use or simply want a more Outlook-inspired workflow, these tools deliver. We've tested them extensively to bring you reliable recommendations based on real-world productivity gains.
In addition to Gmail's built-in labs features, these eight Chrome extensions transform your experience. Note: For a full switch from Gmail to Outlook on Office 365, you can easily import all your Gmail data.
Outlook often handles 'mailto:' links by default on Windows, opening a compose window instantly. Without it, you're prompted to choose an app. The Send from Gmail extension by Google fixes this, routing 'mailto:' links directly to Gmail.

This saves time and adds a toolbar button for quick Gmail sharing of web content—like articles for later reading or colleague recommendations. It's a simple yet powerful upgrade.

Gmail's contact sidebar shines with Google-connected info but falls flat otherwise. Rapportive populates it richly, mimicking Outlook's contact management with seamless integration.

Acquired by LinkedIn (now under Microsoft), it pulls LinkedIn profiles, social links, Skype details, websites, affiliations, and recent updates. Add personal notes and reminders for better tracking—ideal for marketers noting contact context.

Outlook's keyboard shortcuts boost efficiency once mastered. Gmail has them too, but KeyRocket teaches them interactively as you work.

It suggests shortcuts for common actions, like opening a new compose window with a few keystrokes. Over time, you'll navigate Gmail like a pro, just as with Outlook. Free for Chrome; premium extends to other apps like Microsoft Office.

Desktop apps like Outlook run in the background for instant notifications. Checker Plus brings this to Gmail, alerting you to new mail without keeping a tab open.

Get sender, subject previews, and quick actions: mark read, archive, or delete. Chrome's native notifications work too, but this is more comprehensive.

Gmail lets you set signatures per account, but they look plain without design skills. Blade Signatures creates vibrant, professional ones with photos, websites, social profiles, and contact info.

Free version supports two signatures with easy switching; premium or Google Drive customs offer more.
