The Yamadūtas are the constables of King Yama (the lord of death), who punishes all sinful men. Vaiṣṇavas are never called for by such constables of Yamarāja. In the Śrīmad-Bhāgavatam, in the narration of Ajāmila's deliverance, it is said that Yamarāja gave clear instructions to his assistants not to approach the Vaiṣṇavas. Vaiṣṇavas are beyond the jurisdiction of Yamarāja's activities.
The Padma Purāṇa also mentions, "A person whose body is decorated with the pulp of sandalwood, with paintings of the holy name of the Lord, is delivered from all sinful reactions, and after his death he goes directly to Kṛṣṇaloka to live in association with the Supreme Personality of Godhead."
