Mailwell

Mailwell is a native Mac mail app for people with more than one account. Gmail, iCloud, Fastmail, Kagi Mail, Microsoft 365 and any IMAP or JMAP server share one unified inbox. Mail is stored on your Mac and syncs straight to your provider: no Mailwell servers, no tracking, no ads. Inbox tabs, rules, snooze, send later, and undo for everything. AI is optional and off by default. Turn on MCP and Claude can search your mail, read only.
