How this service works
Is the domain's email hosted by mail ru? Looks up the MX records (Cloudflare DoH) and matches them against mail-ru'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 answer indicating whether the domain's email is hosted by Mail.ru, along with the full list of MX hosts found and which specific MX records matched Mail.ru's known mail-exchanger patterns.
Example use cases
Sales prospecting email provider check
“I'm about to reach out to acmecorp.ru — can you check if their email is hosted on Mail.ru so I know which provider they're using before I contact them?”
Pre-migration source provider verification
“We're migrating email for novostnik.ru to Google Workspace. Can you confirm their current MX records point to Mail.ru so we know what we're migrating from?”
Deliverability segmentation by email host
“I need to know if techfirm.ru is using Mail.ru for email — look up their MX records and tell me yes or no, and which Mail.ru exchanger matched.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/mail-ru?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to detect whether a domain uses Mail.ru as its email hosting provider. It is ideal for sales intelligence pipelines targeting Russian-speaking markets, pre-migration auditing when Mail.ru is a suspected source provider, or deliverability segmentation by email host. It returns structured MX data alongside the match result, making it more useful than a generic MX lookup when Mail.ru detection is the goal.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX list
- Cloudflare DoH timeout or DNS resolution failure — lookup may fail with an error
- Domain uses a custom mail gateway that relays through Mail.ru — may produce false negatives
- Malformed domain input — returns validation error
