So, if you send or receive messages to your Gmail inbox in "confidential mode", they will self-destruct (i.e. you can't copy, download or print them) upon the scheduled expiration date. You'll also be able to add a passcode to the email.
Google is also updating its email service with several new features, one of which is a snooze function. Further, the person added, "We need a bit more time to compose ourselves, so can't share anything yet-archive this for now, and we'll let you know when it's time to hit send". While ProtonMail deletes the message completely after a certain amount of time, Google sends a link to the message in the email which becomes inaccessible after a certain amount of time - leaving the intermediate email in the inbox.
Google is reportedly working on an all-new design and feature set for the web version of its email service Gmail.
In a statement, Google did not confirm specific changes but did acknowledge that it's working on a change to its email service.
Walking on the line of other applications like Snapchat, Line and Signal, Gmail is also devising a feature which will let users draft self-destructing emails.
While these "confidential" emails are hard to forward or copy for the sender, it's important to note that there's no word of end-to-end encryption - suggesting that Google can still read the contents of your emails and comply with law enforcement if they're required to give information from your account - so don't send anything you wouldn't be fine with the authorities seeing. On the other hand, Google generates an email with a link in Gmail's current implementation.
Google has confirmed that its Gmail update will come soon hence it is supposed to be available within the coming weeks.
Google is all set to roll out an updated Gmail and the tech giant has already begun notifying some of the G Suite users about the same. It is unclear if the "confidential" expiring mails will be end-to-end encrypted. The Verge notes, though, that recipients will still be able to take screenshots or photos of these confidential emails.
