title: Better way to send email to multiple recipients with AdonisJs
body: <p>I want to send newsletters to multiple users, but when I try my code, the emails can be seen by everyone. And if I send it using looping, I'm afraid it will take a long time because there are many users. Is there a good solution to send multiple emails?</p>
  <p>This is my code (I use SMTP):</p>
  <pre><code>await Mail.send('newsletter', data, (message) =&gt; {
      message
        .from('newsletter@web.com', 'Admin')
        .subject('New Events Notification')
        .to(emails) // array consist of multiple emails
      })
  </code></pre>
