Expire License Email

Hey,
I need to know how the woocommerce plugin works, like if we create license key and assigned to any product which is for 30 days, What we want is email should shoot we subscription or license going to expire after 2 days, so is this condition handled in woocommerce, if yes than how we can check that. If no than how we can handle this condition.
Please provide us proper documentation for this.
