please avoid obectManager

Add this into your My Controller

 protected $emamilHelper;

 public function __construct(
    ..........................................
    \vendor\RequestForQuote\Helper\Email  $emamilHelper,
    ..........................................
) {
    ..........................................
    $this->emamilHelper = $emamilHelper;
    ..........................................
}

Now you can call Your Helper function like this

 $this->emamilHelper->HelperFunctionName(); //  call your helper function
