Spam Eating Monkey SEM-URIRED is a domain and URI blocklist (URIBL) that lists domains and URIs with a high probability of being associated with unsolicited email. This blacklist extends the standard SEM-URI list by including all SEM-URI entries plus additional domains identified through Spam Eating Monkey's higher-risk URI reputation data. Mail server administrators use it to help identify messages that contain suspect links.
Technically, systems query this list through the DNS zone urired.spameatingmonkey.net. A positive match returns the IP address 127.0.0.2. Because this is a URI-focused blocklist, the domain being queried is usually a domain found in a message body or link, not necessarily the SMTP sending IP or the visible From domain. In most configurations, a listing adds to a message's spam score rather than causing rejection on its own.
Listings on this blocklist are policy-based. A domain might be listed because it has appeared in spam campaigns, has been used by known spam groups, does not honor unsubscribe requests, or is tied to list acquisition practices that lack clear consent. The listed domain might be the link domain in the message, not the same domain that authenticated the message with SPF, DKIM, or DMARC.
Who runs Spam Eating Monkey SEM-URIRED?
The SEM-URIRED blacklist is operated by SpamEatingMonkey.com. Spam Eating Monkey provides realtime IP and URI reputation data for mail server administrators. Spam Eating Monkey states that it does not block any mail directly. Instead, it provides reputation information that administrators of recipient mail servers use at their discretion. If your mail is being blocked, the block is the result of a decision made by the administrator of the server you are trying to email.
How do you check a SEM-URIRED listing?
Use a DNS lookup against the SEM-URIRED zone for the exact domain you are investigating. For URI blocklists, start with the hostname found in the email link, then query it as a child of urired.spameatingmonkey.net. A 127.0.0.2 response means the domain is listed. NXDOMAIN, no A record, or an empty response means there is no active listing in that zone for the exact name you queried.

Do not treat a clean result for your sending IP as proof that SEM-URIRED is clear. This blacklist evaluates URI and domain reputation, so check domains used in tracked links, redirects, landing pages, and unsubscribe URLs.
How do I get removed and delisted from Spam Eating Monkey SEM-URIRED?
To request removal from the Spam Eating Monkey SEM-URIRED blocklist, first confirm the exact domain that is listed. Then use the lookup tool on the Spam Eating Monkey website. If your domain is listed, the lookup tool provides access to a delisting form. According to Spam Eating Monkey, removal requests are typically processed within 24 hours. A request can still be denied if the listing is deemed valid.
Before you request delisting, resolve the issue that caused the listing. Review the domain, the URLs used in campaigns, and the mail stream connected to those URLs. Specifically, check for the following:
- Compromised pages, malicious redirects, or campaign URLs that have been abused in spam.
- Link tracking, redirect, landing page, and unsubscribe domains that differ from the visible sender domain.
- Mailing practices that do not honor unsubscribe requests promptly.
- Email addresses acquired through scraping, purchased lists, or other methods that do not involve explicit consent.
- Any association with known spam operations or affiliates sending mail that points to the listed domain.
- SPF, DKIM, and DMARC alignment for authorized mail when the affected domain is also used as a sender domain.
What's the impact of being listed on Spam Eating Monkey SEM-URIRED?
The impact of being listed on the Spam Eating Monkey SEM-URIRED blacklist is generally low to moderate. The service itself recommends that its data be used in scoring systems rather than for outright rejection of mail.
However, the actual impact on your email deliverability depends on how recipient mail servers use this specific blocklist (or blacklist). A listing can cause some messages to be sent to the spam folder because the message score increases. In stricter configurations, it can lead to rejection.
Because SEM-URIRED looks at domains and URIs in message content, authentication alone does not clear the issue. A message can pass SPF, DKIM, and DMARC while still being affected by a listed tracking domain, redirect domain, or landing page domain.
