“totally recommend Invaluement... they block things that get through other filters... Great job - keep it up”
“The only RBLs I trust as strict accept & reject decision making are Spamhaus and Invaluement.”
“You also may want to look at the Invaluement IP/URI lists. ...Detection rate is very good ...FP level is extraordinary.” [which means: mistakes are rare]
“ivmURI and ivmSIP are good solid and professionally operated lists... high effectiveness... extremely low false positives”
block more spam
THE PROBLEM: So you’re blocking almost all spam (ALMOST!), but your users are STILL frustrated with the spams that slip past your spam filter, which can STILL sometimes add up to a sizable number of spams making it to the inbox, in spite of your overall high percentage of blocked spam. Often, certain series of elusive spams will target certain users, and they really don’t care that these egregious spams they keep seeing in their inbox are a tiny percentage of all blocked spam. They want results, not excuses!
FROM BAD TO WORSE: While some of those spams merely annoy your users and waste everyone’s valuable time, even much worse, OTHER such spams can trick users into clicking links that install malicious malware (sometimes ransomware!) or lure them into a phishing scam (possibly compromising your organization’s bank account information!). Often, you’re the one who has to fix that mess, and you may even get blamed for it! Large extra expenses and tedious hours of work are often part of the damages caused by just one such data breach or infection!
As a result, these remaining unblocked spams are causing BIG problems and relentless complaints! And there isn’t an easy fix because...
THESE ELUSIVE SPAMS HAVE THREE PROBLEMS:
- They are often the hardest to block, so they get past many spam filters and DNSBLs!
- Most of the (overly-aggressive!) methods that do block them ALSO block far too many legitimate emails!
- Other solutions that might block these very elusive spams typically require a time-consuming and extremely expensive complete overhaul of your spam filtering system.
THE SOLUTION: Invaluement is the PERFECT solution because (1) our service easily integrates into your existing spam filter and (2) blocks a large portion of these remaining and most elusive spams that even the best spam filters miss. Unlike most other solutions, (3) invaluement does this while keeping false positives at industry-leading extremely low levels.

HOW DOES THIS WORK? Really, you don’t even need to know all the technical details because typically, to implement this, you just copy a particular host name (that we will assign to you), paste that into a form field in your spam filter, hit “save”, and start enjoying better spam filtering. This only takes a few minutes. For most, it is that fast and easy! But if you want more technical details, view our how DNSBLs work page.
