    Simple call a ajax like this 

            var mail = '[email protected]';
jQuery.ajax({
    type: "POST",
    url: "/module/checkemail/",
    dataType: "json",
    data: {email: mail},
    success: function (exist) {
        if (exist == 1) {
            // js for email exists
        } else if (exist == 0) {
            // js for not
        }
    },
    error: function (jqXHR, textStatus, errorThrown) {
                   // error handling
    }
});

    Than make a controller and load customer by email 

    $CustomerModel = $objectManager->create('MagentoCustomerModelCustomer');
$CustomerModel->setWebsiteId(1); **//Here 1 means Store ID**
$CustomerModel->loadByEmail($customerEmail);
$userId = $CustomerModel->getId();
if ($userId) {
    return 1;
} else {
    return 0;
}

i

    if you get true than email exists.

    It seems like you are trying to validate email address as customer enter his email address. For this you just need minor change in the email address field.

    <input type="email" name="email" id="email_address" autocomplete="off" value="<?php echo $block->escapeHtml($block->getFormData()->getEmail()) ?>" title="<?php /* @escapeNotVerified */ echo __('Email') ?>" class="input-text" data-validate="{required:true, 'validate-email':true, 'remote':'<?php echo $this->getUrl('customcustomer/index/uniqueemail', ['_secure' => true]); ?>'}"/>

    Create a controller and add you logic in execute method.

    <?php 
namespace GauravCustomCustomerControllerIndex;

use MagentoFrameworkAppActionAction;

class Uniqueemail extends Action
{
 /**
 * @var MagentoFrameworkControllerResultJsonFactory
 */
 protected $resultJsonFactory;

 /**
 * @var MagentoCustomerModelCustomer 
 */
 protected $_customerModel;

 /**
 * @param MagentoFrameworkAppActionContext $context
 * @param MagentoFrameworkControllerResultJsonFactory $resultJsonFactory
 */
 public function __construct(
     MagentoFrameworkAppActionContext $context,
     MagentoFrameworkControllerResultJsonFactory $resultJsonFactory,
     MagentoCustomerModelCustomer $customerModel
 ) {
     $this->resultJsonFactory = $resultJsonFactory;
     $this->_customerModel = $customerModel;
     parent::__construct($context);
 }

 public function execute()
 {
     $resultJson = $this->resultJsonFactory->create();
     $email = $this->getRequest()->getParam('email');
     $customerData = $this->_customerModel->getCollection()
                   ->addFieldToFilter('email', $email);
     if(!count($customerData)) {
       $resultJson->setData('true');
     } else {
       $resultJson->setData('That email is already taken, try another one');
     }
     return $resultJson;
 }
}

    I hope this will be helpful to you.
