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.

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!

Good so far! Been using for months now, great service and support very responsive. Just a shame their non-free plans are such a big jump up from the free ones.

Battled fraud for years, IPQS is the best! I’ve been battling fraud for years and have tried nearly every service in the industry. Our site accepts payments and also suffers from account abuse during registration. IPQualityScore is the only service we’ve found that can handle all of our fraud detection, while also verifying users during signup. Very impressive team all around and even more impressive technology. It’s easy to block legitimate users and their tools are very careful with avoiding those issues.

IPQS makes it really easy for our team… IPQS makes it really easy for our team to validate payments and ship orders without worrying about the risk from chargebacks. The support team is also great, and I always get a fast response back. Pricing is very competitive and I have no complaints about the service or accuracy.
