Microsoft Outlook
Outlook may not be the most popular email app for iPhone users, but it’s actually incredibly handy, and it comes with a bunch of powerful features to make your work and daily life easier. It’s a great app to use if your job heavily relies on the Microsoft ecosystem, but it’s also one of the best third-party apps for those who need to manage several different types of accounts in one place.
The feature that makes Outlook especially useful is its Focused Inbox, which splits your mail into “Focused” and “Other” so the important stuff stands out. Granted, this feature won’t work perfectly from the get-go, but you can “teach” it which stuff is important and which messages can wait by manually sorting your mail at first.
Besides that, Outlook can sort other types of mail for you. You can quickly access all your messages from subscription services, and even get alerts for when one of your next payments is coming soon, so you don’t accidentally waste money on a platform you don’t really want to use.
