It is important to hire magento developers as they can resolve major and minor issues in magento development in lesser time. In this article, you will learn to send email programmatically in magento 2 like developers do.

In this tutorial, we will learn how to send Email in magento2, we know that in magento 1 how to send email programmatically but in magento 2 their some changes in code.

Let’s me explain you step by step for it.

• Setup your custom module (In my case it is : DK/CustomEmail)
• Now create email_templates.xml in the path app/code/DK/CustomEmail /etc

 <?xml version="1.0"?>  
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../Email/etc/email_templates.xsd">  
 <template id="send_email_email_template" label="Email Form" file="send_form.html" type="text" module="DK_CustomEmail" area="frontend"/>  
 </config>  

• Create send_form.html in the path app/code/ DK /Email/view/frontend/email

 <!--@subject Contact Form@-->  
 <!--@vars {  
 "var data.comment":"Comment",  
 "var data.email":"Sender Email",  
 "var data.name":"Sender Name"  
 } @-->  
 {{trans "Name: %name" name=$data.name}}  
 {{trans "Email: %email" email=$data.email}}  
 {{trans "Comment: %comment" comment=$data.comment}}  

• Create you custom controller and write below code :

 <?php  
 /**  
 * Recipient email config path  
 */  
 const XML_PATH_EMAIL_RECIPIENT = 'contact/email/recipient_email';  
 /**  
 * @var \Magento\Framework\Mail\Template\TransportBuilder  
 */  
 protected $_transportBuilder;  
 /**  
 * @var \Magento\Framework\Translate\Inline\StateInterface  
 */  
 protected $inlineTranslation;  
 /**  
 * @var \Magento\Framework\App\Config\ScopeConfigInterface  
 */  
 protected $scopeConfig;  
 /**  
 * @var \Magento\Store\Model\StoreManagerInterface  
 */  
 protected $storeManager;   
 /**  
 * @var \Magento\Framework\Escaper  
 */  
 protected $_escaper;  
 /**  
 * @param \Magento\Framework\App\Action\Context $context  
 * @param \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder  
 * @param \Magento\Framework\Translate\Inline\StateInterface $inlineTranslation  
 * @param \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig  
 * @param \Magento\Store\Model\StoreManagerInterface $storeManager  
 */  
 public function __construct(  
 \Magento\Framework\App\Action\Context $context,  
 \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,  
 \Magento\Framework\Translate\Inline\StateInterface $inlineTranslation,  
 \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,  
 \Magento\Store\Model\StoreManagerInterface $storeManager,  
 \Magento\Framework\Escaper $escaper  
 ) {  
 parent::__construct($context);  
 $this->_transportBuilder = $transportBuilder;  
 $this->inlineTranslation = $inlineTranslation;  
 $this->scopeConfig = $scopeConfig;  
 $this->storeManager = $storeManager;  
 $this->_escaper = $escaper;  
 }  
 /**  
 * Post user question  
 *  
 * @return void  
 * @throws \Exception  
 */  
 public function execute()  
 {  
 $post = $this->getRequest()->getPostValue();  
 if (!$post) {  
 $this->_redirect('*/*/');  
 return;  
 }  
 $this->inlineTranslation->suspend();  
 try {  
 $postObject = new \Magento\Framework\DataObject();  
 $postObject->setData($post);  
 $error = false;  
 $sender = [  
 'name' => $this->_escaper->escapeHtml($post['name']),  
 'email' => $this->_escaper->escapeHtml($post['email']),  
 ];  
 $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;   
 $transport = $this->_transportBuilder  
 ->setTemplateIdentifier('send_email_email_template') // this code we have mentioned in the email_templates.xml  
 ->setTemplateOptions(  
 [  
 'area' => \Magento\Framework\App\Area::AREA_FRONTEND,   
 'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,  
 ]  
 )  
 ->setTemplateVars(['data' => $postObject])  
 ->setFrom($sender)  
 ->addTo($this->scopeConfig->getValue(self::XML_PATH_EMAIL_RECIPIENT, $storeScope))  
 ->getTransport();  
 $transport->sendMessage(); ;  
 $this->inlineTranslation->resume();  
 $this->messageManager->addSuccess(  
 __('Thanks for contacting us with your comments and questions. We\'ll respond to you very soon.')  
 );  
 $this->_redirect('*/*/');  
 return;  
 } catch (\Exception $e) {  
 $this->inlineTranslation->resume();  
 $this->messageManager->addError(  
 __('We can\'t process your request right now. Sorry, that\'s all we know.'.$e->getMessage())  
 );  
 $this->_redirect('*/*/');  
 return;  
 }  
 }  

(Note: “’area’” is area that you work. If you want to send mail from backend use \Magento\Framework\App\Area::AREA_FRONTEND)
