What is it?

UCEPROTECT is an IP-based blacklist service that identifies and blocks IP addresses suspected of sending unsolicited commercial emails (UCE) or spam. It operates a reputation-based blacklist known as the UCEPROTECT-Level system, which ranks IP addresses based on their alleged involvement in spamming activities and imposes temporary or permanent blocks on listed IPs.

Key points to remember

Key points to remember

  • Blacklist Reputation System: UCEPROTECT maintains a reputation-based blacklist system that categorizes IP addresses into different levels (e.g., Level 1, Level 2, Level 3) based on their alleged spamming behavior and reputation. IPs with higher levels are considered more egregious spammers and may face stricter penalties.

  • Listing Criteria: IP addresses are listed on the UCEPROTECT blacklist based on various factors, including spam trap hits, spam complaints, email volume, bounce rates, and other indicators of spamming activity. Listings are typically temporary but can escalate to higher levels for repeat offenders.


  • Impact on Email Deliverability: Being listed on the UCEPROTECT blacklist can have significant consequences for email deliverability, as many email service providers and ISPs use UCEPROTECT's blacklist data to filter out emails originating from listed IPs. Being listed may result in emails being blocked, bounced, or routed to recipients' spam folders.


  • Listing Removal: IP address owners can request delisting from the UCEPROTECT blacklist by following the prescribed delisting process, which often involves addressing the underlying spam issues, improving email practices, and demonstrating a commitment to responsible email-sending behavior.


  • Controversy and Criticism: UCEPROTECT has been criticized for its aggressive blacklisting practices, including listing IPs without clear evidence of spamming activity and charging fees for expedited delisting. Some organizations view UCEPROTECT as overly punitive and unreliable, leading to disputes over its credibility and impact on legitimate email senders.
