Change email address that has been deleted

[Beaksangeun]

Hello, I was using [removed per the Community's Guidelines] for my e-mail. But the e-mail has been deleted and I can't even log in because I can't authenticate my e-mail. I want to change it to the [removed per the Community's Guidelines] I'm using now. What personal information should I prepare

Without access to the other email its very unlikely you'll be able to gain access to the account.

See https://help.dropbox.com/account-access/lost-email-access and contact support via www.dropbox.com/support while not logged in - even here on forums. You will probably find using an incognito window makes it easier.
