Combines multiple Gmail and Google Workspace accounts into a single unified view inside Gmail, letting you read, search, and reply without switching accounts. Built by mccprogrammer.com, the Chrome extension runs entirely in the browser and follows a privacy-first model. It integrates cross-account search, automatic From-address selection and signatures, attachment previews, templates, snooze and scheduled send. Suited for professionals and power users who handle several accounts and want single-tab email management with local data processing.

Combines accounts inside Gmail to reduce tab switching

Unified Inbox for Gmail merges messages from multiple Gmail and Google Workspace accounts into one integrated interface inside the existing Gmail UI. The extension shows a combined inbox and applies labels and categories per account, so you can manage messages without signing out or opening separate windows. This design preserves Gmail’s native layout while placing cross-account controls where the inbox normally appears.

Keeps email processing local with a serverless design

The extension implements a serverless architecture, which means all token handling and data processing happen within your browser and not on an external server. The developer does not operate servers to process mail, and the extension includes no analytics or tracking. That behaviour limits external data movement to the browser-to-Google connection only, as described by the extension’s privacy approach.

Search, composition, and account handling follow Gmail conventions

The tool hooks into Gmail’s native search box so you can run cross-account searches with standard Gmail operators like from: or has:attachment. When replying or forwarding, it automatically selects the correct From address and signature for the account that received the message, and it supports reusable templates, snooze, schedule send, and a remind-me function across connected accounts.

Notifications, attachment previews, and platform scope

The extension provides desktop notifications that can be color-coded by account, and shows inline previews for images, PDFs, videos, and text files without opening the full message. It is available only as a Chrome extension for desktop (Windows, macOS, Linux), so its behaviour and state depend on the browser profile where the extension is installed rather than on a separate cross-device backend.

A practical local-first option for multi-account Gmail users

Unified Inbox for Gmail suits professionals who want single-tab management of several Gmail accounts and prefer local processing of credentials and messages. Because it runs only inside Chrome and keeps state in the browser, users who need server-side cross-device state or a non-Chrome workflow may find it limiting. For privacy-minded multi-account workflows, it provides a focused, locally executed alternative.
