Better Integration with Specific Services: Clients like Mimestream are built from the ground up for services like Gmail, offering deeper integration than a general-purpose client.
Cross-Platform Consistency: If you use multiple operating systems, an email client available on all of them (like Outlook or Thunderbird) can offer a more unified experience.
Specific Needs: Requirements like advanced security (PGP encryption), team collaboration features, or specific workflow automation tools might not be met by Apple Mail.
Stability and Performance: While generally stable, some users with very large mailboxes or specific configurations might experience issues with Apple Mail, prompting a search for more resilient alternatives.
