The part of the program that really works well for me is that I can get both an email check and an IP check done using the same keystroke as opposed to having to pay for two different services and input two different API keys (as I was doing prior) and I simply enter the list of clients and it will tell me what addresses are good, what are disposable, what are spam traps, what has abuse reports filed against them within the last few days, etc., and the score will be directly adjacent to each address so I won’t have to spend all day guessing which addresses need to be removed. My bounce rate on our outreach efforts fell from around 10% to less than 1%, which is the sole reason I continue to purchase this service. It has also identified numerous Gmail addresses that have experienced abuse recently – and Gmail generally appears to look clean – therefore I probably wouldn’t have found these myself.

I like that it removes these bad accounts prior to sending out emails. My deliverability has gone from about 89% to nearly 99%. I was getting suspended by my isp due to excessive bounces but Ipqs filters the dead emails first. It hasn't disrupted my workflow since my staff began using it. You can simply drag and drop your csv file on to the dashboard.

I only really care about the fraud score line in the API call. I take the users' IP address and their Email (at checkout) and receive a number back along with some True/False Flags. Then I simply use a 90% cut-off to make my decision. This took less than an hour to write in and since I am not a real developer, I simply copied and pasted until it worked. I also liked how it replaced two Paid Subscriptions for me, I was paying One company to validate Emails and Another company to determine the Reputation of IPs. Now, I have one key, one price and that saved me a lot of money as a business. When I lost my test key due to a mistake I got a reply from Support within hours. They responded faster than the previous Vendor I dealt with.
