Custom domains on Yandex 360

Often catch-all - common in CIS businesses

Yandex consumer domains (yandex.ru, yandex.com, ya.ru) are not catch-all. But Yandex 360 business email - widely used across Russia and CIS - allows catch-all configuration on custom domains. BounceZero detects catch-all per domain and applies ML scoring where SMTP can't give a definitive answer.

High Yandex Decay Rates in Eastern European Lists

Yandex and Mail.ru addresses are dominant in Russian-language lists. Both have very high account abandonment rates - users migrate to Telegram, create new Gmail accounts, or simply stop using email. Russian B2B lists built before 2022 have especially high decay rates due to market disruption. BounceZero's live SMTP check identifies which accounts are still active.
