El mail client for iOS Mailbox It has been for a couple of months like a gemstone, everyone wanted it but not everyone had access to it. After being very successful, access to the service was limited and a waiting list was opened, gradually bringing in new users. As incredible as it may seem, after downloading the application, you had to wait for a notification to be able to use it, which in some cases took a month. The waiting list got to be populated with 1 million users. This It's over and now it is directly accessible to everyone.
Its incredible popularity led to Dropbox to take over the companyIt was worth $ 100 million, a clear strategic move followed by a promise to keep the product and improve it where possible. Ten weeks after that acquisition, the work and perhaps a good amount of resources coming from the cloud storage company have made access to the service unblocked and the reasons that led to limiting access disappear, namely a loss remarkable speed in accessing emails. In a short time it reached the incredible figure of 50 million messages a day, which caused a certain collapse. Now Mailbox is capable of delivering 100 million messages per day, thus giving your customers room to communicate fluently.

The application still has its limitations as the only serve to manage Gmail. However, work is being done to increase the number of supported mail services. Its design is optimized for iPhone exclusively, but we don't think it will take too long to arrive on iPad now that Dropbox is monitoring. Some inconsistencies are also detected between the treatment of the emails read in the application and in its browser version.
Either way, your vision of mail messaging as a chat and the speed that this causes have a great projection.
