Answer 1

If you have a custom module use this code:
Mage::getModel('newsletter/subscriber')->loadByEmail($email)->getUnsubscriptionLink();
Explanation:
first part is the model for the subscriber.
If you want to see al the available methods within the model just use this code:
$myModel = Mage::getModel('newsletter/subscriber');
foreach (get_class_methods(get_class($myModel)) as $cMethod) {
echo '<li>' . $cMethod . '</li>';
}
the second part of the code loadByEmail($email) is to get 1 specific subscriber object. $email should be a string of the emailaddress.
The last part of the code is a selfexplaning method. It will generate a link to unsubscribe. This is a method that is given by Magento.

Answer 2

In my Magento version I get the following code by default when creating a new newsletter template:
Follow this link to unsubscribe <!-- This tag is for unsubscribe link -->{{var subscriber.getUnsubscriptionLink()}}
I expect it to work in any Magento version.

Answer 3

I am using Magento 1.9.
To add newsletter unsubscribe link in newsletter template here are following steps:
Override the core file
/app/code/core/Mage/Newsletter/Model/Subscriber.php
by copy in local directory
/app/code/local/Mage/Newsletter/Model/Subscriber.php
Open in editor to edit the code and seacrh the function sendConfirmationSuccessEmail()
replace the code
$email->sendTransactional(
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_TEMPLATE),
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_IDENTITY),
$this->getEmail(),
$this->getName(),
array('subscriber'=>$this)
);
with this
$email->sendTransactional(
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_TEMPLATE),
Mage::getStoreConfig(self::XML_PATH_SUCCESS_EMAIL_IDENTITY),
$this->getEmail(),
$this->getName(),
array('subscriber'=>$this, 'unsubscribe' =>$this->getUnsubscriptionLink())
);
and place this code in email template where you want to use unsubscribe link:
Unsubscribe here
That's it!
Hope this helps someone.
