I would like to have a timestamp stored for when a person subscribes or unsubscribes.

Looking at the database: specifically the table newsletter_subscription I see the field changed_status_at. However, this does not get populated, it is left null.

Evaluating the file /app/code/core/Mage/Subscriber.php I cannot see any reference to this field either.

Doing some research I found this link. However, after placing the suggested solution on the line(s) 350 and 376 of Subscriber.php it makes no difference and was still unchanged. Thus, is this a bug in magento and if so how would I correct this?


After playing around with this, I placed ->setChangeStatusAt(Mage::getModel('core/date')->gmtDate('Y-m-d H:i:s')) before every save call in the file. For example,

            ->setChangeStatusAt(Mage::getModel('core/date')->gmtDate('Y-m-d H:i:s'))

This looks to be setting the changed status date now. But, I can only see it if I go to manage customers. Thus, how could I:

A) do this without editing core files?

B) show this date in Newsletter => Newsletter Subscriptions

I assume that you have altered the newsletter_subscriber table and added the field to store the timestamp.

Answer for part A: By adding an observer to the event newsletter_subscriber_save_before in your config.xml:


You can then call getSubscriber() (see next code block) in your observer to get the Mage_Newsletter_Model_Subscriber model that allows you get data about the subscriber. This works for occurrences of subscription and unsubscriptions.

public function newsletterSubscriberChange(Varien_Event_Observer $observer) {
    $subscriber = $observer->getEvent()->getSubscriber();
    //now do whatever you want to do with the $subscriber

    //for example
    if($subscriber->isSubscribed()) {

    // Your code to set timestamp


Answer of part B: You can extend the newsletter subscriber grid using your custom module and add the new column to show the new field.

You may need to use join in the _prepareCollection() function if you have created a custom table instead of adding the column to the newsletter_subscriber table.
