I haven't used many other email validation products before, only a couple of 'free' cloud-based options with limited list size capability. Kickbox is super professional, easy to use, and works.

WhoisXML API
We use WhoisXML Email Verification API for the additional value it provides to our corporate email security, and we recommend that most organizations do the same. Disposable email services may help protect the privacy of their users, but in the corporate setting, receiving emails from these domains may not be safe. So, aside from flagging emails from domains categorized as spam, we wanted our spam filtering system to be stricter and include disposable email addresses.

WhoisXML API
  • WhoisXML Email Verification API obtains its disposable email detection capabilities from a disposable email domain database that monitors most disposable email providers regularly.
  • WhoisXML Email Verification API is compatible with most spam filtering solutions and other email security systems. It is also available as a Splunk application, so compatibility wasn’t an issue for us.

  • We had to avail ourselves of the custom plan because we have a pretty large user base, and each user receives hundreds of emails per day. We were able to come up with a reasonable agreement, in any case.

I like Kickbox output files better as it includes the "domain". Overall, both softwares could do a better job cleaning lists. Kickbox shows more "unknown" emails where are BriteVerify shows less "unknown emails" but then more bad emails end up in the valid list. Kickbox has a higher threshold to put emails in "unknown".
