VoilaNorbert vs. WhoisXML Email Verification API

VoilaNorbert is great for sales people trying to find email addresses but we use it mainly in a PR capacity. It's best suited in our workflow if you know the site and the person you are reaching out to. In terms of scenarios where it is less appropriate, if you are looking to find related people or related sites to the one you are reaching out to, I haven't explored that functionality.

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.

• Precise email address most of the time
• Easy to use
• Easy to track the usage

• 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.

• Additional subscription options

• 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.

It is more reliable than 80% of the other apps available in the market in terms of generating email address. Some tools like snov.io and others which were not available to on search bar are used for the same, but their result quality is very poor. Even the paid version of such tools are not reliable.

• Improved efficiency on prospecting efforts and outreach
• Ability to reach out to a larger amount of leads in less time
