# Without the Plug-in

1. Open the **„functions.php”** file in your WordPress template.
2. Adjust the code below to your integration credentials and email settings and then paste it into the file.

```
add_action(’phpmailer_init’,’send_smtp_email’);
function send_smtp_email( $phpmailer )
{
 
        	// Information that we are sending via SMTP
 
         	$phpmailer->isSMTP();
 
        	// SMTP server name
 
        	$phpmailer->Host = „smtp.emaillabs.net.pl”;
 
       	        // SMTP authentication (true/false)
 
        	$phpmailer->SMTPAuth = true;
 
      	        // SMTP port number – 25 (no encryption),
 
                //587 (tls encryption)12          $phpmailer->Port = „587”;
 
     	        // EmailLabs smtp account name
 
     	       $phpmailer->Username = „ACCOUNT NAME”;
 
     	        // EmailLabs smtp account password
 
      	        $phpmailer->Password = „PASSWORD”;
 
     	        // Connection encryption – tls
 
                // or do not call the method
 
                $phpmailer->SMTPSecure = „tls”;
 
    	        $phpmailer->From = „Your email address”;
 }
```

In the last step, try sending a test message to ensure that integration was done correctly.
