The responses address the usage of Validity's FBLs, the status of Comcast data, and the implementation of DKIM FBL. AWeber opted out of Validity's FBLs due to perceived ineffectiveness and desires access to Comcast data. DKIM FBL v2 is released, with AWeber showing interest, but the initial draft needs more feedback and development. Monitoring DNS records is suggested as an alternative to routing reports. Major ESPs generally support FBLs, although the reporting quality varies among ISPs. Validity offers FBL aggregation services. FBLs, governed by ARF standards, are crucial for identifying problematic addresses, managing sender reputation, and enhancing deliverability. Comcast blocks senders with poor engagement, emphasizing list hygiene and engagement monitoring. DKIM enhances email authentication, but its impact on deliverability depends on ISP spam filtering algorithms.
