Hi you can do this by magento event Observer and find a trigger an observer on customer save after and fire send your custom transactional email automatically.

You can try this Two Event

  1. customer_save_before

  2. customer_save_after

Find details on event and observer here

Model Approach

Step1: trigger an event on basic of customer_save_after


Step2: Magento Observer Code is

class Stackexchange_Magento37890_Model_Observer
    public function checkDisplay(Varien_Event_Observer $observer){

        Mage::log('My log entry'.$customer->getId(), null, 'Magento37890.log');
        /* if customer  is old customer */
            /* here you write your code to send whenever you have change the group */
        /* New Customer */


  • Checking for $customer->getId() under the event customer_save_after to determine if the customer is new would not work. Since the event is AFTER save, there will always be an id. You can determine if the customer is in fact new by checking the state of $customer->getOrigData() - if it is NULL, there was no previous data, so is assumed a new record.
