Portable mail model
Provider state, local search, drafts and commands are not defined by AppKit.
Brev is a local and programmable desktop email client, but it does not currently run on Windows. The Windows interest list measures demand without pretending a client is available.
No Windows client or download is currently available
Brev separates the portable mail engine from platform-specific interface and credential code. That makes Windows a real product direction while keeping current availability precise.
Provider state, local search, drafts and commands are not defined by AppKit.
Windows still requires supported credentials, packaging, notifications and a desktop interface.
The interest list shows whether Windows users and their provider combinations justify that work.
Brev concentrates on email, durable local state and a scriptable command surface rather than reproducing the complete Microsoft work suite. It is relevant to people who want one focused client for Gmail and standards-based accounts, but it is not a current Outlook or Microsoft 365 replacement.
Choose Outlook, Thunderbird, eM Client or another available client when you need Windows mail now. Register interest in Brev only if its local, provider-aware and programmable approach is the reason you would consider switching.
Register your current client, providers and account count. This is an interest list, not a request for immediate access.
