All about DNSBLs, aka blocklists/blacklists // Since 2001 // Published by Al Iverson
Thanks for visiting! Remember that nowadays, (most) blocklists don't usually govern deliverability and inbox placement on their own. Want to learn more about email marketing best practices, email technology, and deliverability troubleshooting? Then you'll want to check out my other site, Spam Resource.
As I often do, today I'm receiving reports about a DNSBL (which I've previously warned was dead) is returning false positive entries for those still using it today.
