So, if possible and if the sender still has that email, you can ask them to resend it to you.

However, expiring emails always remain in the Sent folder on the sender’s side, unless they delete it.

Thus, it can be the reason why some of your emails are missing from your Gmail account. When the expiration date of the email is reached, that email disappears from the inbox or whatever folder it is stored in on the receiver’s end. Then, the screen will appear, where the expiration date can be set by the sender. One can set the expiration date for an email by clicking on the Confidential Mode icon present near the Send button in the email composing window. The option to specify expiration dates for emails allows for messages to disappear from inboxes after a certain period of time. Emails can be password-protected, sent again, and messages can’t be forwarded, printed, copied, or downloaded by other people, with this mode. This feature is accessible when the ‘ Confidential Mode’ is turned on.
