It is a "plug n play" service and so, you need data, off you go - run a search and you can find the data you need. Install data is an additional cost, but it is available. It covers countries very well and is especially useful where seniority is not a big issue. Classification is pretty good for the most part. Their ABM tool is pretty good too. Review collected by and hosted on G2.com. What do you dislike about Klarity by DemandScience? LOW SENIORITY CONTACTS and HIGH HARD-BOUNCE RATES. High hard-bounce rates exist mostly in regions like the UAE. Nearly 90% bounce and when I told them that that impacted our "sending reputation" and caused problems with the email campaign provider we use, asking for more information why there was such a massive hard bounce rate, I got a rude response, credited 500 free names and basically ignored. Also, when I previously sent bounce data to them, they complained as it had a couple of addresses that had been sent to them previously. Honestly - this service could be great - but the customer service leaves a bad taste for their overall ability. I question the validity of their validation checking and would be very cautious about sending to their data before running it through unbounce or zero bounce or a service like that. Also, I thought they were a GDPR compliant service but I am not sure that they are. Review collected by and hosted on G2.com. Recommendations to others considering Klarity by DemandScience: Better quality checking and improved customer service Review collected by and hosted on G2.com. What problems is Klarity by DemandScience solving and how is that benefiting you? Currently, I am not sure whether Leadiro has benefitted my business other than a few leads - I have spent a fair amount with them but will be cancelling my service with them. They need to work on their customer service and quality checking of their data. Review collected by and hosted on G2.com.
