Zoho Mail offers advanced spam filters that can automatically identify and block spam emails.

Users can customize these filters based on their preferences and also set up whitelists and blacklists to ensure important emails don't get marked as spam.

Zoho Mail's domain-based spam control allows users to set up policies for their entire domain. This means that all emails coming from a specific domain can be filtered or blocked based on certain criteria.

Zoho Mail maintains a real-time blacklist of known spam senders and IP addresses. This blacklist is constantly updated to ensure that users are protected against the latest spam threats.
