UCEPROTECT is one of the most aggressive blacklists around, and it's especially common in Europe. It can list your IP for spam you sent, or for spam your neighbors on the same network sent. Every listing expires on its own, and you never have to pay to get off it.
Free, no signup. See if UCEPROTECT, Spamhaus, Barracuda, or other major blacklists have you listed.
Examples: 203.0.113.42 or example.com
| Blacklist | Status | Response |
|---|
| Level | What It Means | What to Do |
|---|---|---|
| Level 1 | Your IP sent spam to UCEPROTECT's traps. | Fix the cause. The listing expires 7 days after the last spam. |
| Level 2 | Too many IPs in your provider's block are on Level 1. | Ask your provider to clean up their network; it clears on its own once they do. |
| Level 3 | Too many IPs across your provider's whole network are on Level 1. | Only your provider can fix it. UCEPROTECT ignores removal requests from end customers at this level. |
For a Level 1 listing, find what's sending spam from your IP: a hacked email account, malware on a machine on your network, or a website form being abused. Our delisting checklist walks through each one.
Every level expires on its own, free. UCEPROTECT also sells express delisting, but paying is never required. Check your status at uceprotect.net.
A UCEPROTECT listing can land on your IP because of someone else's spam. Generator Labs checks your IPs against UCEPROTECT and hundreds of other blacklists and alerts you by email, Slack, SMS, or webhook when a listing appears, so you can get your provider moving before mail starts bouncing. Free for your first host.
No. Every level expires automatically. Express delisting is optional.
Levels 2 and 3 list whole blocks and networks when too many neighboring IPs spam. Your provider has to fix it.
Seven days after the last spam reaches UCEPROTECT's traps.
