UCEPROTECTL2 is a blacklist that can stop your emails from reaching anyone. If your IP is on this list, your messages won’t even land in spam—they’ll be blocked completely.
This can hurt your business like in case your important emails don’t get delivered, your reputation takes a hit, and you lose opportunities.
But don’t worry—you can fix this. In this guide, you’ll learn:
Let’s get started and get your emails back where they belong—the inbox.
The UCEPROTECTL2 blacklist is a database that identifies IP addresses linked to spam or suspicious activity.
It helps block unwanted emails, protecting users from spam and fake email attempts.
If your IP lands on this list, it means your emails might not even reach the spam folder—they could be completely blocked.
UCEPROTECT uses three levels to flag IPs:
If your IP is on L2 or L3, it’s often due to other users in your network, not your direct actions.

So being blacklisted can hurt your business in three major ways:
The longer your IP stays on this list, the harder it gets to recover.
Now that you understand what UCEPROTECTL2 is, let’s move on to why IPs get blacklisted in the first place and how to address it.
Here are the most common reasons why IPs end up on the UCEPROTECTL2 blacklist:
Hackers can take control of your server or email accounts to send spam without your knowledge.
If your email system isn’t set up properly, it can look like you’re sending spam.
Sending emails to people who didn’t ask for them, especially from purchased lists, can lead to complaints.

If you’re using an IP that was used for spam before, it can carry a bad reputation.

Removing yourself from the UCEPROTECTL3 blacklist can be challenging because it targets entire service providers, not just individual IPs.
If your provider’s network has a high amount of spam, all IPs within that network—including yours—can get flagged.
This means even if you’re not sending spam, you could still be affected.
Here’s what you should do then:
