Dropbox just delivered some bad news for Mailbox users.
The company will shut down its popular email app along with its its photo storage app Carousel, Dropbox announced Monday.
Though neither app has a clear replacement, the company says it will bring some of Carousel's "key features" to the Dropbox app .
Mailbox was already hugely popular when Dropbox acquired it in 2013, but had been struggling to deal will the massive influx of users.
The app is often credited for introducing gesture-based controls to email, allowing you to organize messages by swiping right or left, a design that has been imitated by dozens of email apps since.
