What is MailRUBot?

MailRUBot fetches web resources for the Mail.ru email service. Its recorded user agent is Mozilla/5.0 (compatible; Linux x86_64; Mail.RU_Bot/2.0; +http://go.mail.ru/help/robots), with Mail.RU_Bot as the stable token.

The record describes a mail fetcher, not a crawler that discovers sites for a general index. A request therefore shows that a Mail.ru mail feature needed the URL or resource. It does not show that a Mail.ru user visited the page in a browser, and the available data does not specify which email feature initiated the fetch.

Nothing in this entry assigns MailRUBot an AI search or model-training purpose. Allowing it may let the relevant Mail.ru email workflow retrieve public content, but it does not improve eligibility for AI answers or citations. Blocking it is likewise not a general AI training opt-out.

MailRUBot is recorded as respecting robots.txt. The entry has no verified IP status or request-signature method, so the user-agent string can classify traffic but cannot authenticate it. Keep private mail links, account pages, and other restricted content behind normal access controls.

Indirectly relevant

Is MailRUBot relevant for AI search?

Indirectly. MailRUBot has no AI product of its own, but its output can end up in the systems that AI answers draw on.

MailRUBot fetches pages to build link-preview cards. It does not feed an AI index, but it reads the same Open Graph and structured metadata that AI systems parse to understand your pages, so clean preview metadata doubles as AI-friendly metadata.

How to handle MailRUBot

Allow MailRUBot if Mail.ru email users should be able to retrieve your public content through the feature that calls it. If those requests are unwanted, target the stable token without changing rules for unrelated Mail.ru or VK services:

User-agent: Mail.RU_Bot
Disallow: /

this bot and Cloudflare's matching record both say it follows robots.txt. Check access logs after publishing a rule, since a copied user agent may not be genuine MailRUBot traffic.

Do not use robots.txt to protect sensitive URLs. Require authentication for private resources and enforce any hard denial at the application or edge.

Examples

  • A publisher sees `Mail.RU_Bot/2.0` request a public article after the URL is handled by a Mail.ru email feature.
  • A membership site allows MailRUBot on public help pages while its account and billing routes still require a login.
  • A security analyst labels a matching request as claimed MailRUBot traffic but does not allowlist it from the header alone.
