Creating disposable email address on Gmail, with expiration date

I knew we could create disposable email address on Gmail by appending + to username and adding random characters after that, but didn’t know we could add expiration date to them.

Let’s say your temporary email address is amit@gmail.com. A website form requires your email address so you can put amit+mmdd@gmail.com in the sign-up field where mmdd is the month and date till when that disposable email will stay valid.

For instance, if you specify the email address as amit+0623@gmail.com – that alias will be valid until June 23 and any emails sent to that alias after that date are ignored else they are forwarded to your main Gmail address. You can only specify the year in your temporary email amit+12312020@gmail.com in mmddyyyy format.
