Overview

Batch BlackList is an efficient API for evaluating the reputation of IP addresses and domain names, specifically for mail server and DNSBL (DNS-based Blackhole List) monitoring. It checks addresses against multiple widely-used spam and blacklist services to help identify potential issues with email deliverability or domain/IP reputation.

• Check against well known DNSBLs.
• Check SenderScore.
• Check PTR/A Record.

Supported Blacklists

This API currently supports a wide range of blacklist zones, including but not limited to:

• SpamCop
• SpamHaus Zen
• BARRACUDA
• Abuse.ro
• 0spam DNSBL
