DNS real-time blackhole lists (RBLs) are databases that block emails from suspicious IP addresses or domains to protect against spam and phishing. Signs of being blacklisted include bounce errors, recipient complaints, dropping engagement rates, and spam folder placement. Common causes include high spam complaints, unsolicited bulk emails, open relay configurations, compromised servers, and weak security. To get delisted, identify and fix the root cause, submit a removal request to the blacklist operator, and wait for processing. Prevention strategies include building permission-based email lists, maintaining consistent send patterns, implementing SPF/DKIM/DMARC authentication, and sending relevant content.
