YahooMailProxy
GoodBotVerifiedBOTA proxy service used by Yahoo Mail to pre-fetch and cache content for links embedded within emails to improve user experience and security. Operated by Yahoo.
What is YahooMailProxy?
YahooMailProxy is a specialized service operated by Yahoo that acts as an intermediary between external web content and the Yahoo Mail platform. When a user receives an email containing a URL, this bot fetches the page content to generate link previews and perform security checks before the user interacts with the link. It ensures that the email interface remains responsive and that users are protected from potentially malicious content by pre-scanning the destination.
Identification
YahooMailProxyWhy it crawls your site
The bot crawls websites to extract metadata, such as page titles, descriptions, and images, which are then displayed as rich previews within the Yahoo Mail interface. By fetching this data server-side, Yahoo reduces the latency for the end user and performs necessary security analysis to identify phishing or malware risks. Webmasters can verify the bot's legitimacy by checking the provided Yahoo help documentation and ensuring the requests originate from verified Yahoo IP ranges.
