Get email from user at checkout success page

Question

I am overriding the checkout success page, Vendor/Theme/Magento_Checkout/templates/success.phtml and I want to let the user to know that a confirmation e-mail is send to his/her e-mail address.

Is there any way to show the e-mail address, that the user has filled in the checkout page? I have tried searching for methods like getEmail but could not find anything.

Overwrite Magento\Checkout\Block\Onepage\Success

Vendor/Module/etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Checkout\Block\Onepage\Success" type="Vendor\Module\Block\Onepage\Success" />
</config>

Vendor/Module/Block/Onepage/Success.php

namespace Vendor\Module\Block\Onepage;

class Success extends \Magento\Checkout\Block\Onepage\Success
{
    public function getEmail()
    {
        $order = $this->_checkoutSession->getLastRealOrder();
        return $order->getCustomerEmail();
    }
}

Now inside your success.phtml

<?php echo $block->getEmail(); ?>

Make sure your template is define inside checkout_onepage_success.xml following way:

<block class="Magento\Checkout\Block\Onepage\Success" name="checkout.success" template="Magento_Checkout::success.phtml" cacheable="false"/>

That means Magento_Checkout before success.phtml in template attribute.

Clear cache.
