Mailcheck.co vs. WhoisXML Email Verification API

Well suited scenario: - Easy and clean design - Great email validation quality and speed - Amazing API can be installed on any website form - Nimble support Less appropriate scenario: - Hard to define, the only thing, I believe they need to add more integrations.

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.

• Email validation
• Simplicity
• Logically built UX/UI
• Powerful API

• 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 think more integrations would be good

• 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've been using this service for quite some time, and then I was receiving more bounces than expected. I decided to try solutions like Mailcheck.co and couldn't be more right to choose them, very happy with Mailcheck.
