IPQS is technically a far better solution than anything else I've tried. I compared its results to other providers in a data-driven way and found that it's just a lot better at predicting what emails will be delivered vs bounced. I don't know how they do it, but it involves a lot more than just pinging an email server and play back the response.

I'm also happy with their customer service. They correct any billing issues without hesitation.

I highly recommend this product. Review collected by and hosted on G2.com.

Their interface is very dense and the pricing page even denser. Review collected by and hosted on G2.com.

I use ipqualityscore for email validation and to check ip reputation of my business. And the best thing I like about them is their pricing and the option to mass upload ips in a CSV file to check the IP reputation, which is a great feature. Review collected by and hosted on G2.com.

The only thing I don't like is that the mass upload feature in the free version has a minimal part of 100 uploads only at once. Which I think is pretty low and would be great if it was higher. But you can use the paid version to increase the limit. Review collected by and hosted on G2.com.

They provide the most accurate proxy/VPN detection service that one can find in the market, and the false positive is close to zero. Additionally, the mass-checking option is a great feature that I love about IPQualityScore. Review collected by and hosted on G2.com.

They bill monthly, which is a good thing for the customers. But their basic plan does not include all the features, and you need to upgrade to a higher plan to get them. This is a drawback as the higher plans cost quite a bit. Review collected by and hosted on G2.com.

I like the easy integration into our platform and that it works on the links themselves and not just on, say, google ads. Our contact there has always been responsive and helpful as well, and the pricing is fair. Review collected by and hosted on G2.com.

There are some gaps in the settings that require manual overrides, for lack of a better description. It can be tricky to find out what is just the right strictness. Review collected by and hosted on G2.com.

Ipqualityscore was recommended by a friend who also uses its services. And honestly, till now, I had a great experience using their service. The email validation is very accurate and has excellent documentation on using their API. Also, the IP address fraud score checker is top-notch and gives accurate results.

Their pricing is a bit high, and the website UI could be better. So lower pricing would be much appreciated. But overall, I am very happy with the quality of the service provided. Review collected by and hosted on G2.com.

The only downside that I could find was that they did not update their website UI for quite sometime now. I have gotten used to it, but their UI may be too complicated for new customers. Review collected by and hosted on G2.com.
