Terms of the deal were disclosed. Blog postings from both companies suggested their respective goals were in alignment, making such an acquisition a logical step. “Dropbox doesn’t replace your folders or your hard drive: it makes them better,” read a March 15 posting on Dropbox’s official blog. “The same is true with Mailbox. It doesn’t replace your email: it makes it better. Whether it’s your Dropbox or your Mailbox, we want to find ways to simplify your life.” On its own official blog, Mailbox noted that its service capacity had grown by 2000 percent since launching in February, and that it now delivered more than 60 million emails per day. The app’s creators have ambitious plans that include support for more mobile devices and email providers, along with a host of unnamed features. Dropbox could provide the talent and infrastructure necessary for making those plans become a reality. “Rather than grow Mailbox on our own, we’ve decided to join forces with Dropbox and build it out together,” Mailbox’s posting added. “To be clear, Mailbox is not going away. The product needs to grow fast, and we believe that joining Dropbox is the best way to make that happen.” Mailbox’s team had previously admitted their app’s growing pains. “Software that is server-based is susceptible to being overloaded, and we want to keep this from happening,” they wrote in a blog posting earlier in March. “This is why we still have a line. If you’re waiting in line, know that we’re working as hard as possible to get Mailbox in your hands soon.” Mailbox delivered 50 million emails during its first week of operation, as the app fought to handle the data-flood from its users’ respective email services. That number’s only increased in the succeeding weeks. While Dropbox is a much more established company, with the cloud-based infrastructure to deal with lots of user data at any given time, it may face a challenge in helping support Mailbox’s deluge.   Image: Mailbox
