Hotmail web slice mail

You're referring to the "Hotmail Web Slice" feature!

In the early 2000s, Hotmail introduced a feature called "Web Slices" that allowed users to subscribe to specific parts of a webpage, such as a news feed or a mailbox, and receive updates in their Hotmail inbox. This feature was designed to make it easier for users to stay up-to-date with their favorite websites and services without having to constantly visit those sites.

The Hotmail Web Slice feature worked by allowing users to add a "slice" of a webpage to their Hotmail account. This slice would then be updated periodically, usually in real-time, and the user would receive an email notification with the latest updates. For example, a user could add a Web Slice to their Hotmail account to receive updates on their email inbox, or to stay up-to-date with the latest news from their favorite website.

Unfortunately, the Hotmail Web Slice feature was discontinued in 2012, along with the rest of the Hotmail service, which was replaced by Outlook.com. While the feature is no longer available, it was an innovative way to integrate web content with email and was ahead of its time in terms of web-based services.
