Ninja
Have you been receiving form entries with temporary or invalid email addresses?
Avoid such bad and invalid email leads at the time of capture on your Ninja Forms with the help of Clearout Email Validator!
Using the Clearout WordPress plugin in Ninja Forms can detect and reject :
Misspelled and other invalid email addresses
Temporary, disposable, or throwaway emails that cause bounces
Spam traps, which can damage your sender's reputation, can get you blacklisted
Gibberish emails, which are random email addresses created by spammers, usually
Role-based email addresses that have low value to your sales and marketing
Steps to integrate Ninja Forms with Clearout WordPress Plugin
Log in to your Clearout account, navigate to the ‘Developer’ section. Click on '+Create API Token,' add a name and description, then click Create.

You’ll see the API token. Copy Clearout API Token, then go back to your WordPress site.

Set up the Clearout Email Validator plugin. Go to your form Settings > Clearout Email Validator (make sure you’ve activated the plugin), paste your Clearout API token.
Note: By default, the plugin will block role-based addresses and disposable addresses. You can allow either or both by choosing the checkboxes in the settings.
You can also enable "Accept only Business Address as valid", which will override all the other settings.

Next, if you scroll down, navigate to find the 'Apply Validation' as shown below. Select 'Ninja Forms' for the email validation to perform.

That’s it! Now, when performing a test on your form, it will no longer accept invalid email addresses. Shown below is an example of a Ninja form integrated with Clearout Email Validator. A Gmail address with a typing error has been identified in real-time as invalid, giving the message ‘This email address is invalid or not allowed – please check.’
