Why Switch from Apple Mail?

While Apple Mail is a capable client, especially for those who appreciate its simplicity and integration with the Apple ecosystem, there are several common reasons users seek alternatives:

Limited Advanced Features: Power users often find Apple Mail lacking in areas like advanced sorting, rules, email scheduling, snooze functionality, or AI-driven assistance.
Customization Constraints: Apple Mail offers fewer customization options for its interface and workflows compared to many third-party apps.
Collaboration Tools: For teams, Apple Mail lacks built-in collaboration features like shared inboxes, delegation, or internal comments on emails.
Integration with Non-Apple Services: While it supports standard protocols, deeper integrations with specific services (like advanced Gmail features or Microsoft Exchange capabilities) can be better in dedicated clients.
Specific Workflow Needs: Some users have unique workflow requirements (e.g., intensive use of templates, task management integrations) that are better served by specialized clients.
User Interface Preferences: Some users simply prefer the look, feel, or organizational paradigm of other email clients.
