Listclean vs. WhoisXML Email Verification API

Listclean is best used when you have either scraped or exported a list of leads from a database and need to make sure the emails actually exist. You don't want to be using Listclean if you already have pre-verified contacts from another source like ListKit.

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.

dont know about you, but other services are hard to use for me personally. Obviously cost of Listclean, it's a lot cheaper. And it's easily connectable to lead ads from facebook ads, google sheets and mailchimp.
