Mailbox Currently Delivering 50 Million Emails Per Day


Are you using Mailbox yet? The highly anticipated app launched to much fanfare, although its reservation system has remained a questionable way for it to ramp up its launch; but at the end of the day, this app is free so there’s nothing to complain about.

The company has announced the app is now delivering 50 million emails per day, and during its first week had delivered this number alone:

During its first week Mailbox delivered 50 million emails. Currently, the service is delivering 50 million emails every day. That is an incredible number for a brand new app. For comparison’s sake, Twitter took three years to reach the number of daily messages that Mailbox reached in less than four weeks. Of course, Twitter’s network started from scratch while Mailbox taps into an existing fire hose. Nevertheless, it’s been a massive undertaking to scale 40x faster without a fail whale to lean on.

The reason Mailbox needs to slowly scale its operations is related to the load the app requires to deliver push notifications for emails and “snoozed” messages, in order to have uptime (the service did suffer one short outage already). Mailbox notes they are working hard to further scale and deliver the app to everyone waiting in line.

    I waited patiently to get the app and was actually kind of disappointed in it. I use GMail as my one-inbox solution for email and have GMail set up to send as one of my non-GMail accounts, rather than from my GMail account. I was disappointed that Mailbox would only send from my GMail account and wouldn’t assume my GMail settings of sending from my default non-Gmail account. So I used it for a day and then went back to the GMail app.
