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!

Ruins legitimate website traffic Their VPN/proxy detection data service is very draconian and leads to many false positives that ultimately degrade the service experience of many clients I have worked with, who have had their users' residential and cellular IP addresses falsely assigned a high fraud risk. I myself have had several instances where I have been blocked by sites using data from IPQS despite using low risk corporate or residential IPs, needless to say causing endless headache. I would not recommend using this company for proxy detection unless you are looking to alienate legitimate website visitors. Additionally, they are not very receptive to requests to unblock IP addresses and seemingly have an arbitrary and secretive process by which they assign fraud scores.

Replaced 3 other services we used Very accurate and customizable scoring. The user platform was easy to use as well. We were previously using 3 very expensive API services for fraud prevention to validate new users and payments and still only getting mediocre results. Now we process all of our data through IPQS and we've been very happy with the results.

The best VPN/proxy detection and device… The best VPN/proxy detection and device fingerprint service in the world by far. Not only are their prices the best, but support is the best I've ever dealt with. Been using for 5 years and here's to another 50!

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.
