If you have a Gmail account for personal use and an Outlook account for work — or multiple accounts on both — you already know the problem. You're constantly switching between tabs, missing messages, and losing track of which account a conversation lives in.
A unified inbox should solve this. But most solutions come with trade-offs that make them hard to trust or hard to use.
There are several common approaches to reading multiple email accounts in one place. Each has significant drawbacks:
| Approach | How It Works | Downsides |
|---|---|---|
| Email forwarding | Auto-forward from one account to another | Breaks reply-from addresses, creates duplicates, hard to undo |
| Desktop clients (Thunderbird, Apple Mail) | IMAP/SMTP sync to a local app | Requires installation, tied to one machine, complex setup |
| Server-based unified inboxes (Spike, Mailspring) | Third-party server fetches and stores your email | Your email passes through another company's servers |
| Gmail "Check other accounts" | Gmail fetches mail via POP from other accounts | Slow, limited to POP, doesn't work well with Outlook |
The common thread: most solutions either route your email through a third party, require desktop software, or don't actually work well across Gmail and Outlook.
Remoscope takes a fundamentally different approach to the unified inbox. It runs entirely in your browser. There is no server. Your email never leaves the connection between your browser and Gmail or Outlook's API.
How it works: Remoscope connects to Gmail via the Gmail API and to Outlook via the Microsoft Graph API, both using standard OAuth. Your browser fetches email directly from each provider. Messages are cached locally in your browser's IndexedDB for fast access. No data is sent to any intermediary.
Remoscope's email access is intentionally read-only. This is a deliberate design choice, not a limitation:
This approach means you get the convenience of a unified inbox for reading and searching, with the safety of knowing the app can't change anything in your accounts.
If you manage multiple client email accounts alongside your personal Gmail, a unified inbox lets you see everything in one place without installing Outlook or Thunderbird. You stay on top of client communications without missing personal messages.
Many students have a university Outlook account and a personal Gmail. Switching between them is a daily annoyance. A unified inbox in the browser means you can check both in one tab between classes.
If you've wanted a unified inbox but didn't want your email routing through a third-party server, a client-side approach means your messages stay between you and your email providers. No middleman, no extra copies of your data on someone else's infrastructure.
Dedicated email clients like Thunderbird or Outlook desktop offer full-featured email management: composing, folders, rules, calendars. Remoscope is not a replacement for these tools.
Instead, Remoscope is designed for a specific use case: quickly reading and searching across multiple email accounts in a browser, without installing anything and without handing your credentials to a third party. If you primarily need to read and triage email across accounts, it's a lighter-weight option. When you need to compose or manage, it hands you off to the provider's own interface.
No forwarding rules, no IMAP configuration, no desktop software. Setup takes about a minute per account.
