Overview
SEM Fresh is a real-time blacklist operated by Spam Eating Monkey. Unlike traditional blocklists that track long-term sender reputation, SEM Fresh focuses on detecting and listing IP addresses or domains involved in recent or active spam campaigns.
If your IP or domain appears on this list, mail servers could start delaying, rejecting or routing your emails to spam folders until the issue is resolved. Listings typically expire within 24 hours once spam activity stops, making SEM Fresh an effective but temporary signal of potential abuse, misconfiguration, or compromise.
Removal from the Spam Eating Monkey list
The maximum listing period is 5–30 days, depending on the list. However, most domains and IPs are removed automatically within 24–48 hours after spam stops.
What should I do next? [H3 Heading]
- Do a SEM Fresh blacklist check using an Email Blacklist Checker.
- Check your systems for compromise. Make sure no unauthorized scripts or users are sending mail.
- Review recent mailing activity and sending volume. Look for any sudden spikes in volume.
- Monitor spam complaints to understand how recipients are interacting with your messages.
- Pause bulk sending temporarily.
- Wait for automatic expiration. SEM Fresh does not provide manual delisting; if spam stops, the listing will clear on its own.

Frequently Asked Questions [H2 Heading]
What is SEM Fresh?
SEM Fresh is a real-time blacklist operated by Spam Eating Monkey. It lists recently registered domains and IP addresses associated with spam or suspicious email activity.
How long does an SEM Fresh listing last?
SEM Fresh entries usually expire automatically after 24 hours if no new spam is detected. Other related lists expire in 5–30 days, depending on the list.
Can I manually remove my domain or IP from SEM Fresh?
No, SEM Fresh does not offer manual delisting. Listings expire automatically once the spam activity stops and enough time has passed.
Can I request removal from SEM Fresh?
No, SEM Fresh is an automated blacklist. Once suspicious activity ends, the listing will expire without needing to contact anyone.
Will this hurt my domain reputation and email deliverability long term?
SEM Fresh is designed as a short-term signal, not a permanent reputation penalty. Once the listing expires and your email practices remain clean, most deliverability issues resolve quickly. However, if problems continue, such as high spam complaints or suspicious sending patterns, you may risk future blacklisting by other mail providers, email servers and reputation systems.
I received an error mentioning spameatingmonkey.net. What does this mean?
This means your sending IP address or domain was recently listed on the SEM Fresh blocklist. This list identifies new or suspicious domains and IPs that have been observed sending unsolicited bulk email or potentially unwanted email.
Why did I get listed on SEM Fresh?
If you have been blacklisted by SEM Fresh, it is often because:
- New domains or spammy domain names are being used for email.
- A compromised account or script sent spam.
- Your server sent messages to a spam trap.
- Another sender on your shared IP triggered the listing.
SEM Fresh specializes in flagging recent activity, not historical reputation.
