Users who follow the Yahoo! Terms of Service and our anti-abuse controls can consume an unlimited amount of free email storage. This will apply to both new and existing users.

Our new storage system gives you the option to never delete another email. Unless, of course, you want to. The purpose of unlimited mail isn’t to provide an online storage warehouse. Usage that suggests this approach gets flagged by our anti-abuse measures. In order for our system to work efficiently you may need to create new folders.

Yahoo! employs a variety of anti-abuse methods. If our anti-abuse system detects potential abuse we may take action. These anti-abuse controls enable us to better identify users who are not using the service appropriately under the Terms. Our goal is to ensure that everyone benefits from unlimited storage.
