Summary

The NoSolicitado blacklist is a real-time blacklist focusing on unsolicited email to domains in Latin America, particularly Argentina. While its impact is regional, the broader consensus is that monitoring all blacklists is crucial because even listings on smaller ones can negatively affect sender reputation and deliverability. Assess if the blacklist is actively blocking your mail delivery using logs, and recognize that blocklisting often reflects underlying reputation issues that delisting alone won't fix. Maintain good IP reputation through ethical email practices and follow removal procedures if listed. Determine the value of listing to your mail system by asking questions such as, 'Do any of your customers use them to block mail?'.

Key findings

Regional Relevance: NoSolicitado primarily impacts email delivery to Latin America, especially Argentina.
Deliverability Impact: Blocklists, including smaller ones, can negatively affect sender reputation and deliverability.
Importance of Monitoring: Proactive monitoring of blocklists is essential for maintaining good email deliverability.

Reputation Management: Focus on improving your sending practices to prevent blocklisting from occurring.

What the experts say

4 expert opinions

Expert opinions suggest a practical approach to assessing the impact of blacklists like NoSolicitado. Primarily, check if your mail delivery is demonstrably affected by the listing, using your sending logs. Understand that providers generally don't secretly use public blocklists (except Spamhaus). If blocklisting occurs, it often reflects underlying reputation issues, so address those issues rather than solely focusing on delisting. Monitor your presence on blacklists and if listed, evaluate its real-world impact by considering factors like whether your customers use the list to block mail.

Key opinions

Delivery Impact: The most important factor is whether the blacklist listing actually prevents your mail from being delivered.
Direct vs. Indirect Impact: While providers don't secretly use most public blacklists, being listed often reflects underlying reputation problems that can affect deliverability independently.
Root Cause: Addressing the issues that caused the blocklisting is more effective than simply delisting.
Value of Listing: Assess the true impact of a listing by considering if your recipients use that specific blacklist.

Key considerations

Log Analysis: Regularly analyze your sending logs to identify delivery issues potentially caused by blacklists.
Reputation Management: Focus on improving your overall sender reputation by adhering to best practices, such as proper authentication, spam trap monitoring, and CAN-SPAM compliance.
Proactive Monitoring: Implement a blacklist monitoring system to detect listings early.
Customer Impact: Understand whether your target audience is affected by a specific blacklist.
