According to the Reddit user, they received the screenshot from a Google engineer that has an internal build of Gmail. The screenshot shows a toggle for pinned emails at the top, either an archive-all or clear-all button next to the pinned emails toggle, and a reminder above what looks to be an email bundle.
Inbox users will recognize these features as those that are part of the soon-to-be defunct app.
However, some are questioning the validity of the leak due to the jumbled mess that is the UI. For example, it’s strange to see pins and stars when they might carry out the same action within Gmail.
Also weird to see is the archive-all/clear-all button. As Droid Life points out, it makes sense to see that button in Inbox due to the way it breaks down emails by day, week, and month. It doesn’t make as much sense to see that button in Gmail, though some will nonetheless appreciate the option.
Lastly, what looks like an Inbox bundle is not — it looks to just be a label for “Tech news.”
It’s possible to chalk all of these quirks to this being an early internal build that Google will continually test. The Reddit user that posted the leak also insinuated that they have a way to verify the screenshot.
Even so, Inbox users should take this leak with a grain of salt.
