Hi the blockchain.info wallet offers automatic email wallet backups. As emails are just sent in plain text does this mean anyone sniffing your internet traffic could intercept the email backup easily and steal your wallet? If so is the GoogleDrive backup option a better idea then email backups?
The email backups are sent AES encrypted with your password as the decryption key. It is no easier to get into the email backup of the wallet than it is to login to the website, assuming you have a good password.
