Hunter vs. WhoisXML Email Verification API

Hunter.io is very well suited for any sales rep who is building out lists of contacts for email outreach, or for marketer's looking to reach out to PR and marketing contacts for link building campaigns. The tool is a great free option if you are doing targeted, 1:1 personalized outreach and you need a few contacts. The tool can be expensive if you are needing to reach thousands of people. A paid version of Hunter.io is not a great fit if you already pay for another list building source such as Data.com or Discover.Org.

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.

• Provides email domains very well. While some companies have a different domain for their "info@xyz.com", Hunter is able to find the domain that is being used by individuals at the company.
• For American contacts in particular it is very good at finding personal phone numbers.
• Helps to enrich the contacts that might be in a company by providing a confirmed list of employees.
• As an extra - I really like how easy it is to use. You can input the contacts name and copy-paste from the chrome extension quickly and easily. This saves a load of time when you are trying to find the right address.

• 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.

• There have been times when I've search Hunter for an address on a website and it came back with no results. Then If I search the site I've often found an email address or two. So I'm curious why it wasn't able to find it with the tool, even when I could on my own?
• I'm not sure what the reasons were exactly why LinkedIn ordered the cease and desist, but I had hoped they two companies could come to terms or that at the least LinkedIn would acquire Hunter. But alas, it's not been the case.

• 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.

Prompt and professional support.

Hunter is a much more user-friendly version of Clearbit. I personally also find it to be more accurate than Clearbit. With Clearbit it felt like too many clicks to get to the information that you wanted. With Hunter, it is a simple copy - paste - click, to get the information you need. The additional list of contacts it provides and the verification source is also more readable.

• Hunter has vastly improved my efficiency as a seller. It saves a lot of time for a lot of different reasons.
• The ability to confirm target email addresses saves valuable time having to re-send the same email to one person with multiple different attempts.
• Hunter has a pretty generous free trial ability, which is worthwhile in order to try before you buy.
