Magento 2: Disable Welcome Email Using preference [closed]

Question

How to Disable Customer Welcome Email Only Using preference not with plugin

Answer 1

You can create your preference like so:

<?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\Customer\Model\EmailNotification" type="Vendor\Module\Model\NoEmailNotification" />
</config>

and then override the newAccount method as follows:

<?php
namespace Vendor\Module\Model\Onepage;

class NoEmailNotification extends \Magento\Customer\Model\EmailNotification
{
      /**
     * Don't send email with new account related information
     *
     * @param CustomerInterface $customer
     * @param string $type
     * @param string $backUrl
     * @param int|null $storeId
     * @param string $sendemailStoreId
     * @return void
     * @throws LocalizedException
     */
    public function newAccount(
        CustomerInterface $customer,
        $type = self::NEW_ACCOUNT_EMAIL_REGISTERED,
        $backUrl = '',
        $storeId = null,
        $sendemailStoreId = null
    ): void {
        return;
    }
}

Which essentially inverts the original functionality of the method linked here (https://github.com/magento/magento2/blob/cd826aa2215e19d543a3a606aebde18fa3e40d4e/app/code/Magento/Customer/Model/EmailNotification.php#L384)

So the customer no longer receives a welcome email
