A computer (or device of the like), on behalf of a user, registers the user with a first web site. The computer provides a first email address for use to register the user with said first web site. The computer, on behalf of the user, registers the user with a second web site. The computer provides a second email address, separate and distinct from the first email address, for use to register said user with said second web site. In alternate embodiments, the computer, in like manner, facilitates designations of first and second email addresses for use to electronically communicate with first and second intended communication partners. Co-related, an email service provider receives emails for the first and second email addresses of the user, and organize the received emails by at least the email addresses, and by intended versus non-intended CP/GCP of the email addresses. The email service provider provides these received emails to the computer used the user, with the emails so characterized accordingly. The computer presents these emails for viewing by the user, including in one embodiment, facilitation of deletion of all emails addressed to an email address received from senders other than the intended CP/GCP, via a single press of a key/control button.
