Why Is YahooMailProxy Visiting My Website?
Someone shared a link to your page. YahooMailProxy fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
Should I Block YahooMailProxy?
Usually not. Blocking YahooMailProxy may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. For context, 7% of the top websites we track currently have robots.txt rules for YahooMailProxy.

Frequently Asked Questions
What Traffic Patterns Should I Expect From YahooMailProxy?
YahooMailProxy usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does YahooMailProxy Follow Robots.txt Rules?
No. YahooMailProxy is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is YahooMailProxy Used for AI Model Training?
Not ordinarily. YahooMailProxy is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking YahooMailProxy Affect AI Search or Citations?
Not directly. YahooMailProxy's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does YahooMailProxy Access Private Content?
No. YahooMailProxy has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From YahooMailProxy?
Agent Analytics tracks YahooMailProxy visits in real time. You can also check your server logs for requests whose user-agent string contains "YahooMailProxy". Look for a page and its preview assets being requested without follow-up navigation. Because YahooMailProxy does not publish a verification method, any client can claim its identity and a log match is only a clue.
