 <p>Slight modification to @maxim-lanin's answer. You can use it like this, fluently.</p> <pre><code>\Mail::send('email.view', ['user' =&gt; $user], function ($message) use ($user) { $message-&gt;to($user-&gt;email, $user-&gt;name) -&gt;subject('your message') -&gt;getSwiftMessage() -&gt;getHeaders() -&gt;addTextHeader('x-mailgun-native-send', 'true'); }); </code></pre>
