The quest for the ideal email companion can feel overwhelming due to numerous options available, but the right app can transform your email experience. I tested and compared various iPhone email apps, considering factors such as inbox maintenance, spam filters, organization features, and AI capabilities. The top picks include Mail by Apple for a no-frills experience, Outlook for a balance between simplicity and features, Gmail for integration with other Google apps, Triage for quick and easy inbox maintenance, Chuck for extensive inbox maintenance, Shortwave for AI assistance for Gmail users, BlueMail for organization, Edison Mail for frequent travelers and shoppers, Canary for using AI to write emails, and Proton Mail for privacy and security. Each app has its unique features and pricing plans, so it's essential to try out a few options to find the one that suits your needs.
