Frequently Asked Questions

Common questions about Clearout Email Validator – Real-Time Email Verification on WordPress Forms

Real-time email verification refers to the process of confirming the authenticity or existence of an email address account in real time. Its results are based on real-time analysis rather than on basic checks against the old & existing databases.

This Email Validation plugin listens to email address capture flow for all major forms by hooking WordPress is_email() function to verify whether the user's typed email address can be accepted or not. Behind the screen, the verification will be carried out using Clearout API and the results will be matched with the appropriate settings allowed by the plugin.

Clearout status other than “invalid” will be considered as “valid” email address and the form submission will be allowed. Also, by default, the email address of “disposable” or “role” will be considered as “invalid.” These settings can be changed in the plugin settings.

No, Clearout email validation cannot prevent bad emails from entering your system in the following conditions: 1. If email validation takes longer than the specified timeout value 2. If the status of email validation is returned as unknown

This requires a minimum WordPress version of 4.6, tested and compatible with the latest version.

We strive to bring Clearout email validation support to all major WordPress forms, in case if you see your form is not listed let us know (us@clearout.io). Alternatively, you can try using Clearout Form Guard to bring support of email validation to any form with little or no coding effort

The API token is a unique representation of your access to Clearout Email Validation Service. The API token can be created or obtained by '+ Create API Token' from the Developer menu.

Once logged in to your Clearout account click on 'Developer'–> Click on '+ Create API Token'–> Provide the required details –> Click on Create and the API token will be generated.

Yes. For testing, you can find test email addresses to confirm that your integration works as intended without incurring credits.
