What MultiMail is — and isn't
MultiMail is an independent desktop app. It wraps the web versions of Gmail, Outlook and any mail service you add into one window — and adds the tools they're missing.
MultiMail is
One app for all your webmail accounts — the same Gmail you know, in a real Windows window
A layer of extra tools on top: notifications, switching, Snippets, Scratchpad, AI assistant
Private — you sign in directly with your provider, mail never touches our servers
MultiMail isn't
An official app from Google or Microsoft — it's independent and works with any provider
A classic desktop client like Thunderbird or Outlook — it doesn't download your mail over IMAP or rebuild the inbox. You get the real web Gmail you already know, just better organized
A mail server — your account, password and messages stay with your provider
Questions
Does MultiMail read or store my email?
No. You sign in directly with Gmail, Outlook or your provider inside the app. Your credentials and mail stay between you and them — nothing passes through our servers.
Is it a desktop client like Thunderbird?
No — and that's the point. MultiMail doesn't sync your mail over IMAP or replace your inbox with its own. It runs the real web version of Gmail, Outlook or any provider in one desktop window, with each account isolated, plus notifications and productivity tools on top. Nothing to import, nothing to re-learn.
Which providers are supported?
Gmail, Google Workspace, Outlook, Hotmail, Yahoo, Proton, iCloud, GMX, Zoho and 20+ others. If it has a web inbox, it almost certainly works.
What do I get for free?
Two accounts, notifications and full switching — forever. Premium unlocks unlimited accounts, removes the promo banner and adds Snippets and Scratchpad. The AI assistant is part of the subscription plan.
Is Lifetime really one payment?
Yes — pay once, keep it forever, including updates. Buy it in the app (30-day money-back guarantee, no questions asked) or through the Microsoft Store (refunds follow Microsoft's policy).
Does it work on Windows 10?
Yes, Windows 10 and 11. The download is about 80 MB and installs from the Microsoft Store in under a minute.
