Top iPhone Email Apps to Elevate Your Productivity in 2025

The Official App: ​Mail

Apple's free Mail app is a reliable, solid email app for the iPhone. The Mail app offers simple solutions that are good for most needs.

You can sort out VIP senders (which you define) and file emails to folders. Compose your emails using rich text and swipe to take action fast. Most importantly, you get beautifully rendered emails without clutter and almost no learning curve.

While Mail lacks advanced customization, it supports Exchange, IMAP, and POP. It also includes Apple Intelligence features like priority messages, summarizations, and smart replies.

Manage Multiple Email Accounts: Microsoft Outlook

While many email apps for iPhone feel sluggish even with the basics, Outlook for iOS progresses beyond them. Search with near-instant results and read, send, and file mail fast. The intelligent inbox lets you see the most important emails first, and you can postpone emails with a simple swipe.

This app comes with a calendar, which is simple and functional but lacks task management. As on the desktop version, you can extend functionality with add-ons.

Outlook for iOS is the best email app for iPhone in an enterprise environment. It supports Exchange and IMAP accounts, although POP isn't supported, and works with Gmail, Yahoo Mail, and iCloud in addition to Microsoft Exchange, Microsoft 365, and Outlook.com.

Long-Running Apple Editors' Choice: ​Spark Mail

The designation "Editors' Choice" designation by Apple tells a lot about the Spark Mail app, which offers numerous useful features. When you first open Spark, you are presented with an inbox grouped automatically by category.

You get one-tap replies, swiping actions (including an option to snooze email), and fast search results, which you can save as smart folders. Calendar integration lets you view your schedule and set up events from emails. The customizable actions and push notifications for every email account are superior, and there's an AI writing assistant to help you craft the best messages.

Spark supports IMAP and is available as a free download, while premium packages are available for enterprise environments. These capabilities, along with email signature options, make Spark worth a try.

Stay Organized With Labels and Lists: Airmail

Airmail does everything, it seems, and then some. When it comes to organization and productivity, you can organize folders by labels, turn emails into to-do items, add them to the calendar, and schedule email delivery using Exchange, IMAP, POP, and Gmail.

This app also offers control over managing contacts and email customization. Choose to block senders, undo emails you've sent, snooze emails, or lock your email. Airmail also offers an easy way to send attachments from cloud storage and displays an email's complete source code.

While Airmail includes a smart, filtered inbox, its implementation isn't the most elegant. Search is unstructured and not that smart, and Airmail could help more with smart email templates or text snippets.

Best for Professional Use: Polymail

​Polymail comes in several pricing tiers and with a host of traits geared toward professionals. Notable features include email and attachment tracking to scheduling delivery and message templates.

No matter the account, Polymail lets you postpone emails for later reading. Like a few other often-used functions, you can access this feature from a swipe menu of customizable actions.

If you're particular about inbox organization, the Polymail inbox is strictly a plain list of emails sorted by date. Though you can filter it to show only unread emails, it never organizes or groups itself. And while Polymail supports IMAP, it lacks Exchange account support.

Fast Search and Filters: Edison Mail

​The Edison Mail app is a fantastic email program that gets the important things right, including support for Exchange and IMAP.

While it isn't the digital assistant it claims to be, it does suggest recipients based on frequency and can filter and use emails by type: bills, booking, shipment notifications, as well as email subscriptions.

This app lets you find all messages fast (search is speedy and useful), delete the whole bunch in an instant, and unsubscribe with a single tap. When you read newsletters and marketing emails, you can block read receipts.

To save emails to read later, Edison Mail offers convenient snoozing, and when you tap Send too fast, the app lets you undo it.
