Send email from custom module in Magento2

[Vivek Singh]

Hello All,

First Create a file in etc folder email_templates.xml

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

Then create a controller file or helper file where you want to write a code for sending email

<?php

/**

namespace CompanyName\ModuleName\Controller\Adminhtml\Index;

class Sendmail extends \Magento\Framework\App\Action\Action
{

    /**
     * Recipient email config path
     */
    const XML_PATH_EMAIL_RECIPIENT = 'test/email/send_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;
    protected $_encryptor;

    /**
     * @var \Magento\Framework\Escaper
     */
    protected $_escaper;
    protected $_userFactory;

    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 $scopeConfig
    )
    {
        parent::__construct($context);
        $this->_transportBuilder = $transportBuilder;
        $this->inlineTranslation = $inlineTranslation;
        $this->scopeConfig = $scopeConfig;
        $this->_escaper = $escaper;
    }

    public function execute()
    {
            $this->inlineTranslation->suspend();
            try {
                 /*Here we prepare data for our email*/
                 /* Receiver Info */
                $receiverInfo =['Receiver Name'=>'Receiver Name','Receiver Email'=>'Receiver Email'];
                /* Sender Info */
                $senderInfo  =['Sender Name'=>'Sender Name','Sender Email'=>'Sender Email'];
                $templateVars =array('name'=>$name,'email'=>$email);
                $templateOptions = array(
                    'area' => \Magento\Framework\App\Area::AREA_FRONTEND,
                    'store' => $this->_storeManager->getStore()->getId()
                );
                $transport = $this->_transportBuilder
                    ->setTemplateIdentifier('send_email_email_template')
                    ->setTemplateOptions($templateOptions)
                    ->setTemplateVars($templateVars)
                    ->setFrom($senderInfo)
                    ->addTo($receiverInfo['email'],$receiverInfo['name'])
                    ->getTransport();
                $transport->sendMessage();
                $this->inlineTranslation->resume();
                $this->messageManager->addSuccess(__('Mail Sent Successfully!'));
                $resultRedirect = $this->resultRedirectFactory->create();
                $resultRedirect->setRefererOrBaseUrl();
                return $resultRedirect;
            } catch (\Exception $e) {
                $this->inlineTranslation->resume();
                $this->messageManager->addError(__($e->getMessage()));
                $resultRedirect = $this->resultRedirectFactory->create();
                $resultRedirect->setRefererOrBaseUrl();
                return $resultRedirect;
            }
        }
    }

Hello @Vivek Singh

To send an email we should use SMTP, so why we have to create this module?

Hello @Manish Mittal

This is useful when we want to send email from particular module or creating a custom button for sending email.
