Clearout vs. WhoisXML Email Verification API

This is the only email cleaning program that we use. This is mandatory if you are doing large amounts of emailing two new cold prospects. We have an extremely low balance rate from our emailing system. Clear out is our go-to program to do this and, without question, saves our email URLs for a longer period of time.

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.

• Very easy to use with a nice user interface
• Customer support is excellent, very responsive when you need something
• Email validating highly accurate
• Good value for the money - can go monthly or buy credits ad hoc

• 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.

• Sometimes have errors with certain inboxes
• Learning curve with new software
• Can be hard to set up with organization-locked inboxes

• 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.

This is the only email cleaning system we use.
