Verify emails and more at IPQualityScore I'm completing a small project for a church and needed to verify 1500 email addresses before we sent our first email blast to the 1500 registered users. The staff provided me with a quick and easy solution, and I was able to verify all email addresses within minutes. I recommend ipqualityscore.com for all of your website Fraud verification and email needs. Their API response time is quick, and the information is accurate and trustworthy. Great job!

This service provider classifies IPs… It was quite an act to reach anyone from IPQs at all, the background is that many scammers try to blackmail IPQs by means of bad ratings that the IPs are listed positively again. The best way to send a false positive report to IPQs is either to write to the co-founder on LinkedIn or to create an account with IPQs and submit a support request. Also prove that you are the legitimate owner IP and do not belong to a proxy/BotNet. e.g.: Registration number of the company in your own country, screenshots of the server and IP address in the admin panel of the hoster "remove important info!", proof that the local IP is registered to your own company It remains at -2 stars due to the major problems that the whole thing caused. Original problem: This service provider classifies IPs with a score of 99 without any proof or evidence. My e-mail to the False Positive Team and the request for evidence for this classification has not yet been responded to. A check of the IP with other service providers has also not revealed any anomalies. An inquiry to our ISP has also provided no evidence that there is any problem that IpQualityScore claims to have.

Predatory/Scam I don't know what kind of predatory/scam IPQualityScore.com is or why they have targeted my IP address but I have repeatedly tried to contact them and have heard nothing back.I will not pay them for targeting me.DO NOT TRUST. To update the situation,after reading this review I was contacted by IPQualityScore.com and they quickly corrected erroneously blacklisting my IP address. Advice for anyone falsely being blacklisted by a company like this,I had to write this negative review for them to respond to me and fix their error.There seems to be a lack of laws and regulations regarding private companies falsely blacklisting individuals IP addresses.If you are experiencing this and the company ignores you or refuses to work with you on fixing it you can file a complaint with the FTC or the FCC depending on your situation.

GREAT TEAM, VERY ACCURATE DATA! Our company tested IPQS against 10+ service providers to determine the best IP address data and then again against 15+ service providers for email validation. IPQualityScore outperformed by a significant margin across both services (email + IP). We were also impressed with the quick response times from their support team and our account rep. Their data is a much higher caliber than what's typically found in the industry and you can see that the team works hard to maintain their edge against fraudsters.

A blatantly false classification I had my home IP address falsely classified as "high risk", a "VPN" and a "spammer" and as a consequence had my registration for a web site cancelled, and had the administrator of that web site call me a "liar". I have since had an extended email correspondence with the Technical Director of IPQS who has provided no data whatsoever to justify the "VPN" and "spammer" classifications, and for the "high risk" classifications has provided a port scan (which does NOT match an independent port scan) and a browser profile (which matches my own PC but falsely claims I have bad-actor extensions installed), and has somehow extrapolated what are at best (even if the data was correct) mild indications of an untypical home user into a "high risk" user, a "VPN" and a "spammer". In short, their methodology apparently said (based on the flimsiest of evidence) that my usage looked vaguely like that of bad-actors, and thus I must be one too. This is akin to saying that someone is a thief based on the shape of their ears or the bumps on their head. Based entirely on this mis-classification, I then had my registration for a web-site cancelled, and the administrator of that web site explicitly called me "a liar". In short, my internet usage and reputation were both harmed by a false classification by this company of my internet usage as "high risk", a "VPN" and a "spammer". BE WARNED - since their classification is apparently based on extrapolation rather than any proof that will stand up in a court of law, you run the risk of being sued if you use their data to prevent someone using your services in any way shape or form that impugns their reputation. Note: IPQS response to this review is to deny my email domain name exists. That is the level of their technical inabilities.
