Yahoo Mail 4.0 is out: revamped UI, smarter search, multiple mailboxes, rich compose & more

Yahoo Mail 4.0 for iOS all devices

Yahoo today launched a thoroughly redesigned Mail app for the iPhone and iPad which brings out a number of interesting feature additions and enhancements.

The new, much-improved Yahoo Mail 4.0 features password-free sign-in, way smarter search, contacts management, rich compose, the ability to use multiple mailboxes from services such as, Hotmail and AOL Mail, to name just a few.

“This month marks Yahoo Mail’s 18th birthday and we’re celebrating the occasion by giving you a brand new Yahoo Mail app that’s fast, intuitive and beautiful,” Yahoo said.

“The new app is fully redesigned. It’s more powerful, yet simple to use. And, of course, we’ve made a significant investment in the technology that powers the app, so it’s fast and responsive.”

And in addition to speed, smarts and support for multiple mailboxes, the app marks the introduction of something called Yahoo Account Key, basically a more secure and simple future alternative to the old password that simplifies the sign-in process.

Attention to detail

There’s indeed a lot to be excited for about Yahoo’s new Mail experience. In addition to cleaning up the interface so it’s easier on the eyes and more elegant than before, the app will now show the sender’s initials from a photo curated from Flickr’s image library.

You can swipe right on a message to mark it read or unread, long-tap to select multiple messages at once, check the latest headlines by tapping the Yahoo News icon in the top right corner and more.

If you tap anyone in an email, you’ll get their rich contact details that they’ve shared with you, such as name, company, title, email history and even recent tweets, regardless of whether or not the sender is in your address book.

Smart search

Yahoo Mail’s new search lets you find a message, photo or attachment with a few taps.

“Most people search for things by the sender (either person or company), so we’ve made that the fastest and easiest way to search,” explains Yahoo. “Give us a couple of letters of a person’s name, and we’ll suggest the most likely contact.”

I’m happy to report that the much enhanced search feature does work as advertised. I particularly like how search results are organized into messages, photos and attachments I’ve exchanged.

When you’re searching by keyword, the app makes smart suggestions. Yahoo says these results get more relevant over time as the system searches across your messages, photos and attachments.

Rich compose

Now when you create a new email message in Yahoo Mail 4.0, you can now long-tap the Compose button to quickly send yourself an email. This is an excellent little gem of a feature, especially if you email yourself various reminders throughout the day.

Next, there’s a new plus button for adding photos and videos from your photo library.

By default, your media is scaled automatically but if you want to add photos and videos as standard attachments rather than inline content, tap the “…” on the photo to convert a photo or video to a regular attachment.

Manage multiple accounts

At long last, Yahoo Mail on both mobile and desktop supports third-party email providers, including, Hotmail and AOL Mail. Upon connecting these accounts, you’ll be able to use Yahoo Mail’s search, smart contacts, auto-suggest and rich compose across all your email accounts.

Password-free sign-in

This is a really, really cool feature. Instead of typing in your credentials in order to use Yahoo Mail on your iPhone, the app takes advantage of a new secure sign-in system referred to as Yahoo Account Key.

Yahoo Account Key lets you access your Yahoo accounts from mobile devices without typing in your password. Instead, Account Key uses push notifications to provide a fast and secure way to access your Yahoo accounts.

In a blog post, Dylan Casey, Yahoo’s Vice President of Product Management, said Account Key is more secure than the traditional password because it prohibits anyone from signing in to access an account without the verification that Account Key provides.

It couldn’t be simpler: you just have to tap on ‘Yes’ or ‘No’ to confirm your identity.

Once you activate Account Key – even if someone gets access to your account info – they can’t sign in. And should you lose your iPhone, you can still verify your identity through an email or SMS sent to alternative accounts and numbers.

Account Key is now available globally in the new Mail app and will be rolling out to other Yahoo apps later this year.
