How to change custom sender mail id in magento 2

In Magento 2, you can change the custom sender mail ID by modifying the send_email method in the Magento\Framework\Mail\Template class. Here are the steps:

Method 1: Using Magento's built-in configuration

Go to Stores > Configuration > Advanced > System > Mail > Sendmail
In the From Email field, enter the custom sender mail ID you want to use.
Save the configuration.

Method 2: Modifying the send_email method

Create a custom module by creating a new directory in app/code and adding a registration.php file with the following content:

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
 \Magento\Framework\Component\ComponentRegistrar::MODULE,
 'YourModule',
 __DIR__
);

Create a etc/module.xml file in the same directory with the following content:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/moduleconfig.xsd">
 <module name="YourModule" setup_version="1.0.0">
     <sequence>
         <module name="MagentoFramework"/>
     </sequence>
 </module>
</config>

Create a etc/email.xml file in the same directory with the following content:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/email.xsd">
 <template>
     <send_email>
         <arguments>
             <argument name="from_email" xsi:type="string">[email protected]</argument>
         </arguments>
     </send_email>
 </template>
</config>

In the from_email argument, enter the custom sender mail ID you want to use.

Run the following command to deploy the changes:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy

Clear the cache by running:
```
php bin/magento cache:clean
```

After following these steps, the custom sender mail ID should be used when sending emails from your Magento 2 store.
