WhoisXML Email Verification API vs. ZeroBounce

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.

At the outset of my position with my current company, we used a marketing automation system that was known as a swiss army knife: it could do many things, but none of them well. They had no built in functionality for boosting email deliverability. Digging in to find out what we could do to improve our authority, we learned we needed to clean our lists before sending. ZeroBounce does everything we need it to, and at a reasonable price. What more could you want?

• 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.

• Bulk List validation up to 25 IDs per action is useful in some situations, as we don't want to create a CSV file every time, and for this smaller number.
• We sometimes use the email Finder option when we can't find an email for a person on any other platform.

Incentivized

• 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.

• Navigating among bulk validation, CSV upload, and single-ID validation is hard, and sometimes finding them or switching between them can be made more user-friendly.
• Results: After bulk validation, we receive the results in a Zip file, which is useful sometimes but not every time, as we have to un-zip, and there will be a different CSV file for each result. The final results can be made simple, like email ID in column A, results (valid or Invalid) in column B.

For the large suite of services that they offer their system is pretty easy to understand and navigate. ZeroBonce is also NOT one of those services that is constantly tweaking their UI and making it hard to find tasks that you regularly use. More complex tasks can be more challenging but that's understandable. They also have an extensive restful API that if technical enough allow you to automate some of your most used tasks. They stand behind their product with good documentation as well as high quality customer service.

Prompt and professional support.

We have used ZeroBounce for about 18 months and it works flawlessly. We are able to get all of our questions/issues answered immediately. Felt very comfortable with the product immediately - used their web site which walked us through it and were able to get up and running within minutes. I really haven't had any issues that required support.

We considered AtData since it was recommended by a colleague who has used it in the past. We ultimately ended up going with ZeroBounce based on the cost and documentation/resources available. Email validation tools are probably very similar, but ZeroBounce seemed the simplest for us, and we needed to implement one fast, so activation time was very quick.

Incentivized

• Our deliverability is approximately 99% on most emails we send thanks to ZeroBounce
• We've had an increase in our domain reputation
• The price is affordable and similar to other tools that do the same, but are not as accurate as ZeroBounce
