How this service works
Is the domain's email hosted by yandex mail? Looks up the MX records (Cloudflare DoH) and matches them against yandex-mail's mail-exchanger patterns, returning yes/no, the MX hosts and which matched. Provider detection for deliverability, sales and migration work. $0.01 per lookup.
Output
Returns a yes/no indicator of whether the domain's email is hosted by Yandex Mail, along with the full list of MX hosts discovered via Cloudflare DoH and a subset showing which specific MX hosts matched Yandex Mail's known mail-exchanger patterns.
Example use cases
Sales prospecting by email provider
“I'm building a list of companies that use Yandex Mail so I can target them with a migration offer — can you check if the domain techfirm-moscow.ru is hosted on Yandex Mail and show me which MX records matched?”
Pre-migration email provider audit
“Before we start the migration project, can you verify whether globaltrade.ru currently uses Yandex Mail for its email hosting by checking the MX records?”
Deliverability research for a domain
“I'm troubleshooting email deliverability issues with a partner — can you tell me if their domain partner-co.ru is running on Yandex Mail infrastructure?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/yandex-mail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-domain check specifically for Yandex Mail provider detection. Prefer this over generic MX lookup tools when you need a clear yes/no answer about Yandex hosting with matched records surfaced. Use the bulk sibling endpoint when checking more than one domain at a time. Choose this over manual DNS tools when you need programmatic, agent-friendly provider detection for sales, deliverability, or migration workflows.
Side effects
- Domain does not exist or has no MX records — returns no match with empty host list
- DNS resolution failure via Cloudflare DoH — may return an error or inconclusive result
- Domain uses Yandex Mail under a custom or whitelabeled MX hostname not in the pattern list — false negative possible
- Invalid or malformed domain input — returns error response
- Network timeout reaching Cloudflare DoH — lookup may fail or time out
