Bring Fastmail, Gmail, Microsoft 365 / Outlook, ProtonMail, and generic IMAP accounts into one unified inbox, with the polish of a premium client and architecture built for real-world email. MULTIPLE ACCOUNTS, ONE EXPERIENCE See everything in one timeline or drill into a single account when you need focus. Switch providers without switching apps. NATIVE WHERE IT MATTERS Built as a real native mobile experience. Responsive gestures, solid offline behavior, and attention to the small details that make daily email less painful.
