Laravel - Notifications - Formatting Mail Messages

If a notification supports being sent as an email, you should define a toMail method on the notification class. This method will receive a $notifiable entity and should return an Illuminate\Notifications\Messages\MailMessage instance.

The MailMessage class contains a few simple methods to help you build transactional email messages. Mail messages may contain lines of text as well as a "call to action". Let's take a look at an example toMail method:

     * Get the mail representation of the notification.
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
    public function toMail($notifiable)
        $url = url('/invoice/'.$this->invoice->id);
        return (new MailMessage)
                    ->line('One of your invoices has been paid!')
                    ->action('View Invoice', $url)
                    ->line('Thank you for using our application!');
Note we are using $this->invoice->id in our toMail method. You may pass any data your notification needs to generate its message into the notification's constructor.

In this example, we register a greeting, a line of text, a call to action, and then another line of text. These methods provided by the MailMessage object make it simple and fast to format small transactional emails. The mail channel will then translate the message components into a beautiful, responsive HTML email template with a plain-text counterpart. Here is an example of an email generated by the mail channel:

When sending mail notifications, be sure to set the name configuration option in your config/app.php configuration file. This value will be used in the header and footer of your mail notification messages.
