A URL in your message is listed on URIBL
A domain referenced inside your message body is on URIBL (URI blocklist). Your IP may be clean, but the content is flagged.
URIBL blocks based on URL reputation, not sender reputation. If your email includes a short-link, tracking URL, or redirect through a flagged domain, the entire message is blocked — regardless of how pristine your sending setup is.
What causes it
- You used bit.ly or a similar URL shortener for a link that was later abused by someone else.
- Your email service provider's click-tracking domain was listed.
- A link in your newsletter points to a compromised customer site.
- You attached or embedded a document hosted on a flagged file-sharing service.
How to fix it
Step 1: Identify the listed domain
Visit uribl.com and submit the URLs from your email to see which specific one triggered the block.
Step 2: Remove or replace the URL
Replace shortened URLs with direct links. Audit all tracking domains in your mail. If your ESP's tracking domain is listed, open a ticket with them immediately.
Step 3: Request delisting (if you own the URL)
If you own the flagged domain, visit uribl.com and request removal. Expect to document what caused the listing and what you did to fix it.
