Definition - What does Spam Account mean?
A spam account is a secondary email account that is used for sign-up pages when people don’t want to give their primary email address. The reason people use a spam account for sign-up is because some sites sell email addresses or bombard them with promotional emails that have little or no value. A spam account, therefore, acts as a buffer, allowing the person to access a program, content or service that requires registration while keeping their main email address spam-free.
Techopedia explains Spam Account
A spam account can be useful even when using trusted websites. Users can use a spam account to try out a newsletter, program or service; if they like what they receive, they can change their account settings to redirect that content to a primary email address. The availability of free Web mail accounts has made it easy for users to set up spam accounts. The concept of a spam account has since inspired a similar strategy for online transactions in the form of a firewall account.
