Google is once again opening up invites to try out their recent Inbox app. It is currently accepting all requests to try out their Gmail-based email management app from now until 3 pm Eastern time (noon Pacific time) today.
All you have to do is email email@example.com sometime during that time period and Google should send over your Inbox invite. If you are unsure if you want to try out Inbox, be sure to check out our editor-in-chief Phil Nickinson's hands-on impressions of the app that he wrote back in October.
