Magento – Magento Newsletter Subscription Confirmation NOT sent

Search the file /app/code/core/Mage/Newsletter/Model/Subscriber.php

copy the whole content to

MyVendor/Tweaks/Newsletter/Model/Subscriber.php

Then find the below

public function confirm($code)
    {
        if($this->getCode()==$code) {
            $this->setStatus(self::STATUS_SUBSCRIBED)
                ->setIsStatusChanged(true)
                ->save();
            return true;
        }
        return false;
    }

And replace it with:

public function confirm($code)
    {
        if($this->getCode()==$code) {
            $this->setStatus(self::STATUS_SUBSCRIBED)
                ->setIsStatusChanged(true)
                ->save();

                $this->sendConfirmationSuccessEmail();
            return true;
        }

        return false;
    }

The solution lies in disabling GLOBAL accounts, but rather setting them to WEBSITE level.

This can be done under System>Configuration>Default>Customer Configuration>Share Customer Accounts

This does sound as a bug though. Because on the 1 side of should be able to allow for GLOBAL ACCOUNTS, whilst on the other side one should be allowed to subscribe to different newsletters. These two are unnecessarily mingled now...

This piece of code breaks the registration of the email to the second store.

if ($ownerId !== null && $ownerId != $customerSession->getId()) {
     //'This email address is already assigned to another user.
}
