Well, the answer is really soon now. Today, the team rolled out a smart reservation system to make sure they can gracefully launch the service to the hundreds of thousands — perhaps millions — who are undoubtedly going to want it ASAP.
Unfortunately, this system means that some will have to wait longer than others. But at least there will be some transparency in the process: with Mailbox’s reservation system, you’ll be able to see exactly where you are in line to get the app — both the number of people in front of you and behind you.
Once again, trust me, it will be worth the wait. And yes, the app will be free.
