I need to get the customer e-mail address in the checkout.
I need it after the user went to Step 2 of the checkout (After he entered Address/before he can select his payment option).

I tried:

$quote->getCustomerEmail()
$this->session->getQuote()->getCustomerEmail();
$quote->getBillingAddress()->getEmail();

And many more.

The thing is: The e-mail is nowhere, I used XDebugg and looked deeply in Session, Quote and many more data. But the e-mail address is available after the user clicks on "place order", this is way to late.

I found unsolved questions with the same problem:

Magento2 : How to get guest email address after shipping address and before placeorder?

Probably I have to change Magento checkout behavior, so that it also sends the e-mail together with the shipping address to the controller, because it only sends the address without the e-mail.

BUT, I've no idea, how I can do this.

Edit:
I've tried the answer (Method2) of Rakesh Jakhar, but it seems I do something wrong.

I created the File /app/code/Myself/Test/Model/Customer/AccountManagement.php:

<?php

namespace MyselfTestModelCustomer;

use /* same as original file */

/**
 * Handle various customer account actions
 *
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 * @SuppressWarnings(PHPMD.TooManyFields)
 * @SuppressWarnings(PHPMD.ExcessiveClassComplexity)
 */
class AccountManagement extends MagentoCustomerModelAccountManagement

 /**
 * @var CustomerRepositoryInterface
 */
 private $customerRepository;

 /**
 * @var MagentoStoreModelStoreManagerInterface
 */
 private $storeManager;

 /**
 * @inheritdoc
 */
 public function isEmailAvailable($customerEmail, $websiteId = null)
 
 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $checkoutSession = $objectManager->get('MagentoCheckoutModelSession');
 $checkoutSession->setGuestCustomerEmail($customerEmail);

 try 
 if ($websiteId === null) 
 $websiteId = $this->storeManager->getStore()->getWebsiteId();
 
 $this->customerRepository->get($customerEmail, $websiteId);
 return false;
 catch (NoSuchEntityException $e) 
 return true;
 
 

I added to my di.xml:

<preference for="MagentoCustomerModelAccountManagement" type="MyselfTestModelCustomerAccountManagement" />

The class seems to get overridden, because in the checkout it now says "You already have an account with us. Sign in or continue as guest.".
So I think the method or class is broken now.

Edit2:

So I tried Rakesh Jakhar method 1. But I did it wrong.
Where did I the mistake?

I copied /vendor/magento/module-checkout/view/frontend/web/js/view/form/element/email.js to /app/code/Myself/Test/web/js/view/form/element/email.js.

I added the cookie:

/**
 * Callback on changing email property
 */
emailHasChanged: function () 
 var self = this;

 clearTimeout(this.emailCheckTimeout);

 if (self.validateEmail()) 
 quote.guestEmail = self.email();
 checkoutData.setValidatedEmailValue(self.email());
 $.cookie("checkoutemail", self.email());
 
 this.emailCheckTimeout = setTimeout(function () 
 if (self.validateEmail()) 
 self.checkEmailAvailability();
 else 
 self.isPasswordVisible(false);
 
 , self.checkDelay);

 checkoutData.setInputFieldEmailValue(self.email());
,

Then I probably did the mistake.
I created /app/code/Myself/Test/view/frontend/requirejs-config.js
with the following content:

var config = 
 map: 
 '*':
 
 'Magento_Checkout/js/view/form/element/email.js':'Myself_Test/js/view/form/element/email.js'
 
 
;

The override don't work, the original email.js file is loaded in the checkout. (I executed the setup:upgrade command only, because I'm in developer mode.)

Method 1.

When a custom enter email the following file function are called to validate the email

Magento_Checkout/web/js/view/form/element/email.js

Look the function

emailHasChanged: function () 
 var self = this;

 clearTimeout(this.emailCheckTimeout);

 if (self.validateEmail()) 
 quote.guestEmail = self.email();
 checkoutData.setValidatedEmailValue(self.email());
 
 this.emailCheckTimeout = setTimeout(function () 
 if (self.validateEmail()) 
 self.checkEmailAvailability();
 else 
 self.isPasswordVisible(false);
 
 , self.checkDelay);

 checkoutData.setInputFieldEmailValue(self.email());
 ,

Inside this function quote.guestEmail gives you the email, you can fire an ajax and save that in seesion and use.

Another option saves the email in the browser cookie

$.cookie("checkoutemail", self.email());

and retrieve the cookie value.

Method 2.

Override the following file:-

MagentoCustomerModelAccountManagement.php

Replace the following function:-

public function isEmailAvailable($customerEmail, $websiteId = null)

 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $checkoutSession = $objectManager->get('MagentoCheckoutModelSession');
 $checkoutSession->setGuestCustomerEmail($customerEmail);
 try 
 if ($websiteId === null) 
 $websiteId = $this->storeManager->getStore()->getWebsiteId();
 

 $this->customerRepository->get($customerEmail, $websiteId);
 return false;
 catch (NoSuchEntityException $e) 
 return true;
 

Use the following to retrieve the email:-

$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$checkoutSession = $objectManager->get('MagentoCheckoutModelSession');
$guestEmail = $checkoutSession->getGuestCustomerEmail();
