Why Yandex 360 appears in this category
Yandex 360 for Business — leading corporate mail in CIS markets, free tier widely used.
We classify it as a mailbox provider from primary MX record (lowest preference) matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Yandex 360 is a business email and productivity platform operated by Yandex, Russia's largest internet company. It bundles mailbox hosting with calendar, file storage, and collaboration tools, targeting small and mid-sized businesses primarily across the Russian-speaking region.
Yandex 360 appears as the primary MX record holder for a material share of domains in the top-1M website ranking, though its presence is concentrated in the long tail rather than among the largest global brands. Its adoption skews heavily towards the .ru namespace and Russian-language geographies, making it a key consideration for senders and infrastructure operators working with Russian audiences or monitoring regional email flows.

Regional concentration and inbox testing priorities
Yandex 360's footprint is predominantly Russian and leans towards smaller organisations rather than enterprise or global-scale domains. For senders targeting Russia or Russian-speaking users, including Yandex 360 in pre-send inbox testing is essential to catch regional filtering quirks and ensure compliance with its reputation systems. For global senders, it sits lower on the testing priority list compared to Gmail, Outlook, and other mainstream providers, though regional campaigns should never skip it.
