This article covers, how to send email programmatically in your Drupal 8 site. There are two main steps to send an email using Drupal 8. First we need to implement hook_mail() to define email templates and the second step is to use the mail manager to send emails using these templates. Let's see an example for sending an email from the custom module, also the following name spaces.

use Drupal\Core\Mail\MailManagerInterface;
use Drupal\Component\Utility\SafeMarkup;
use Drupal\Component\Utility\Html;
 * Implements hook_mail().
function module-name_mail($key, &$message, $params) {
  $options = array(
    'langcode' => $message['langcode'],
  switch ($key) {
    case 'node_insert':
      $message['from'] = \Drupal::config('system.site')->get('mail');
      $message['subject'] = t('Your mail subject Here: @title', array('@title' => $params['title']), $options);
      $message['body'][] = Html::escape($params['message']);

Here, the variables $key, $message and params can be described as :

  • $key: An identifier of the mail template.
  • $message: An array to be filled in. Elements in this array include: id, to, subject, body, from, headers
  • $params: An array of parameters supplied by the caller of drupal_mail().

Now lets create a custom function to send the mail using mail manager.

function custom_function_name() {
  $mailManager = \Drupal::service('plugin.manager.mail');
  $module = 'module-name';
  $key = 'node_insert'; // Replace with Your key
  $to = \Drupal::currentUser()->getEmail();
  $params['message'] = $message;
  $params['title'] = $label;
  $langcode = \Drupal::currentUser()->getPreferredLangcode();
  $send = true;

  $result = $mailManager->mail($module, $key, $to, $langcode, $params, NULL, $send);
  if ($result['result'] != true) {
    $message = t('There was a problem sending your email notification to @email.', array('@email' => $to));
    drupal_set_message($message, 'error');

  $message = t('An email notification has been sent to @email ', array('@email' => $to));

Hope this helps, also checkout how to configure SMTP in Drupal 8 using swiftmailer Module

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also. Drupal Technical Apache htaccess SEO Add new comment
