Summary
Experts and email marketers offer mixed perspectives on the impact of UCEProtect listings on SendGrid IPs. Some experts consider UCEProtect to be unreliable, suggesting that legitimate senders shouldn't be overly concerned, especially with Level 3 listings that affect entire IP ranges. These experts recommend focusing on deliverability to major ISPs instead. However, other marketers point out potential temporary deliverability issues and emphasize the importance of proactive monitoring, particularly given that UCEProtect can impact entire ASNs. Best practices, a good sender reputation, and using tools to check reputation are highlighted as crucial for avoiding blacklisting in general. Actions such as reducing spam complaints, warming up new IPs, identifying the cause of any blocklisting, and maintaining a low bounce rate are consistently recommended.
