Magento - customer_save_after always fired twice

Question

I am using the customer_save_after event in magento, and all is working fine apart from 1 annoying thing - it is always fired twice.

There are no other

Answer 1

The difference between these 2 events is one of them can't get customer info, while the other can. So the solution is

    public function email_CustomerRegister(Varien_Event_Observer $observer){

        $customer = Mage::getSingleton('customer/session')->getCustomer();
        $customer_email                 = $customer->getEmail();


        if(empty($customer_email)){
            return;
        }

        // do something
    }
