    public $message;
    public $files;
    public $customfrom;
    public $subject;
    public function __construct($message, $customfrom, $subject, $files = [])
    {
        $this->message = $message;
        $this->files = $files;
        $this->customfrom = $customfrom;
        $this->subject = $subject;
    }

    public function build()
    {

        $email = $this->from($this->customfrom)
            ->subject($this->subject)
            ->markdown('mails.planner-template')
            ->with([
                'message' => $this->message,
            ]);

        foreach ($this->files as $file) {
            $email->attach($file);
        }

        return $email;
    }
