About

YahooMailProxy retrieves and caches webpage content from URLs embedded in Yahoo Mail emails, improving security and reducing bandwidth usage for email users. You can see how often YahooMailProxy visits your website by setting up Dark Visitors agent analytics.

Should I Block YahooMailProxy?

Probably not. If you block a fetcher, it won't be able to fetch the metadata it needs to display a link preview. Fewer people will click on the link to your website without this.

How Do I Block YahooMailProxy?

⚠️ Manual Robots.txt Edits Are Not Scalable

New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.

Set Up Automatic Robots.txt

You can block YahooMailProxy or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
