The new e-mail platform is being rolled out on an exclusive, invite-only basis.
Google only announced the app two days ago, but it’s already pushing out a second wave of invitations.
The search engine giant tweeted this last night: “The second round of invites have left the building. Check your Gmail. Didn’t get one? Hang tight, more on the way.”
Some people have reported that the invites are showing up under Gmail’s ‘Promotions’ mail-sorting tab, so it’s worth checking in there to make sure you don’t disregard it as worthless spam.
If you want an invite, you’ll need to send Google an e-mail at firstname.lastname@example.org requesting one.
There’s no guarantee an invite will turn up in your inbox, but if one does, you’ll then be free to download the app and enjoy the new service.
Google’s Inbox by Gmail is its latest take on cleaning up your e-mail inbox.
It sets out to filter and sort your e-mails into a raft of sensibly named categories, hopefully making it much easier to get to grips with your inbox.
Categories include travel, purchases, finance, and social, making tracking down flight info or an old receipt a relative breeze.
