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!

Seems like a nice service, after all There were some initial problems creating an account, but they kindly helped me, and I'm currently reviewing the service's features before deciding on the paid plans. For now it seems like a great deal.

The best fraud detection service I've been using IPQS for nearly 2 years now and I'm confident to say that it's the best fraud protection/invalid traffic filter out there. I run a few websites and I monetize their content using display banners, mainly from Google Ad demand. Anybody that works as a publisher for Google Adsense/Google AdExchange knows how sensitive Google is when it comes to invalid traffic, and it's ultimately our job to make sure our traffic is clean and legitimate. That's why I use IPQUALITYSCORE services to filter out bots, proxies, and VPNs from my websites. Just include a simple JS tag or PHP file and you are all set. I've tested similar services, but IPQS was the one with the most accurate detection and fewer false positives. I really recommend them.

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!

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.
