Listclean vs. WhoisXML Email Verification API

It's definitely a cheap and easy to use provider to validate emails and mailling lists. A must use if you work with email marketing or even if you simply want to use your old emailing lists to confirm if you can still use it. Anyone can use and it requires no special skills or knowledge.

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.

• The UI/UX is simple and straight forward.
• The pay as you go credit is very cost friendly
• Cross checked the results - pretty accurate

• 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 tried to verify my 4-5 email (which i have used and closed 10 years ago) on Listclean and Listclean provide the acurate status that those emails were dirty

• 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.

I have used MillionVerifier to verify my emails in the past. Compared to Listclean it is much slower. It took nearly thirty minutes to verify a relatively small list of leads. Listclean also has a much faster signup process and is better at verifying catch all emails
