VoilaNorbert vs. WhoisXML Email Verification API

It is great to use when a single email address is needed and for bulk leads as well. It has great integration with the third party tools that makes it easy to manage things and keep track of things. We can even generate campaigns through this.

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.

• Finds email addresses
• Backs up email addresses with other contact info if it exists
• Keeps a database of all of your contacts added

• 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.

• {I feel] it needs an update on the database as sometimes it gives inaccurate results
• Sometimes the Chrome extension clashes [in my experience]

• 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've never had any issues personally, but I know that any of my other colleagues have had quick support after emailing.

Prompt and professional support.

I've used a handful of other products, one is called Hunter.io. Another is called BuzzStream. Both have their advantages. Hunter we've used as a backup to finding emails if VoilaNorbert can't find them. BuzzStream does have nice email finding capabilities, but they are also more robust from an emailing and tracking perspective. I know that VoilaNorbert has some of that functionality but BuzzStream's is more intuitive. But I think VoilaNorbert's email address capabilities are probably faster/better than the other two.
