Key Differences: Microsoft Outlook vs Fastmail
- • Outlook follows a freemium model with advanced security, compliance, and AI Copilot features available through Microsoft 365/Enterprise plans, whereas Fastmail is subscription‑based, privacy‑focused, ad‑free, and emphasizes custom domains, aliases, and masked addresses.
- • Outlook integrates tightly with Microsoft 365 services (OneDrive, Teams, Office apps), while Fastmail supports standard protocols (IMAP/SMTP) and provides business administration tools such as shared addresses and user management.
