"Working on an email service is hard as you have to be compatible with all sorts of email providers and email clients". Apparently, the new self-destructing emails feature which will allow the users to put a timestamp to their mails after which the email won't be available anymore has been termed as the "Confidential Mode" in Gmail. The feature could be called "confidential mode". It is still not clear whether the Gmail service users will be able to send the confidential/self-destructing emails to the other email platforms or not.
"You can configure the expiration date so that your email disappears after 1 week, 1 month, multiple years, etc.", Tech Crunch writes. The addition of Confidential Mode will grant users greater control over the emails they send, giving them the option of adding password protection to a message so they can not be opened by unauthorized people. However, the feature is still under development, as the option "Learn More" now redirects to a blank page.
TechCrunch says that it is unclear if this new feature will work with emails sent to non-Gmail users. The report describes that on the recipient's side, the person used the existing version of Gmail and received a link to view the confidential email.
As of now, it's unknown whether the feature is going to be compatible with non-Gmail users.

Gmail's expiring emails will most likely be deleted from the recipient's inbox once expires.
End-to-end encryption is also not mentioned by Google anywhere.
You'll be able to snooze emails so that they reappear in your inbox hours or days later. The Verge notes, though, that recipients will still be able to take screenshots or photos of these confidential emails.
