What is Yahoo Mail?

The Yahoo Mail Proxy is a specialized agent operated by Yahoo that acts on behalf of users within the Yahoo Mail platform. When a user receives or composes an email containing a URL, this service fetches the target page to extract metadata, such as Open Graph tags, page titles, and thumbnail images. This allows the email interface to display a rich, interactive preview of the link rather than a plain text URL, improving the utility and visual presentation of shared content.

Helpful — It enhances the user experience in Yahoo Mail by generating rich link previews, such as titles and images, for shared content.

Why it crawls your site

This bot crawls specifically to support the 'link preview' feature in Yahoo Mail. It does not perform broad site indexing or deep crawling; instead, it performs targeted, single-page requests triggered by user activity. Website owners can verify the authenticity of this traffic by checking the User-Agent string against the official documentation provided by Yahoo, which confirms the bot's role in rendering previews for their mail service.
