The day has finally arrived: Mailbox, the once red-hot email startup, is no more. After nearly three years of helping us in our (often futile) quest for inbox zero, Dropbox has officially shut it down.
Luckily, in those three years, email apps have come along way -- thanks at least in part to Mailbox's influence. So while you may not be fully prepared to delete the app and start anew, a lot of great alternatives are worth considering.

Whether you love custom swipes and snoozing emails for later or you're all about the inbox organization, these apps can do it all.
Outlook
Outlook is one of the best email apps out there. That's because it's based on Accompli, the email app Microsoft acquired at the end of 2014. The app does a little bit of everything; multiple inboxes are a breeze. Plus, it has one of the best priority inboxes outside of Gmail, which Outlook calls a "focused inbox." You can also customize your swipes, schedule emails you want to come back to later and quickly browse your contacts and recently opened attachments.
Standout feature: Its built-in calendar, which allows you to easily move between your email and calendar without leaving the app. You can also use the calendar to send your availability over email.
Supported accounts: Microsoft Exchange, Office 365, Outlook.com, Gmail, Yahoo, and iCloud
Spark
If inbox zero is your jam, you may want to give Spark a try. You can snooze emails for later or deal with them in batches, as the app will automatically organize things like newsletters so you can move them all to the trash at the same time. It's also super customizable and has a design that's both minimalist and fresh -- not an easy feat for an email app.
Standout feature:The sheer number of customizations features. Like Mailbox, you can customize the actions for both short and long swipes.
Supported accounts:Gmail, Exchange, Yahoo, iCloud, Outlook and other IMAP providers
Cost: Free on iOS
Inbox
Google's newest email app is all about making your email a little smarter. The app has lightning fast search, built-in reminders and the ability to snooze emails for later and highlights, which shows you important details from your messages without opening them. The app will even write some of your replies for you.
Standout feature: Inbox's "Bundles," which intelligently groups similar emails -- like travels reservations, receipts or messages from financial institutions. This lets you check all your bills at once, for example, and then delete them in one swoop when you're finished.
Supported accounts: Gmail and Google Apps
Airmail
Airmail does a solid job of handling the basics (multiple accounts, notifications, filters and folders) along with customizable swipes, and has the ability to snooze messages for later. You can customize just about every feature of the app, from how your inbox looks to what happens to a message after opening it.
Standout feature: The app has hooks into more than a dozen productivity apps, so you can easily send emails to your calendar, to-do list apps or cloud storage account. You can also export them as PDFs right from your inbox.
Supported accounts: Gmail, Exchange, IMAP and POP3
Cost: $4.99 on iPhone; $9.99 on Mac
Gmail
If you rely on Google as your email provider, Gmail is the obvious choice (though the Android app also supports email from other types of accounts). Compared with some of the others on this list, the app is on the simple side, but Gmail is fast (especially on Android) and handles all the basics of email quite sufficiently. It also has one of the best priority inboxes and spam detection, which can greatly reduce the amount of time you spend sifting through unwanted messages.
Standout feature: Google Now. Though it's not technically part of Gmail itself, enabling Google Now lets Google tap into the contents of your inbox to proactively add reminders. If you have a flight reservation, for example, Google Now can send you a reminder about when to leave for the airport the day of your flight, even if you never opened the original message.
Supported accounts: Gmail and Google Apps; Yahoo, Outlook.com and other IMAP and POP accounts (Android only)
