Extends Magento by a new Block to unsubscribe from the Newsletter - by default Magento allows Unsubscription only for logged in users, not for guests.
Additionally, the module adds a frontend route to unsubscribe via dynamic link from within newsletters via shopdomain.tld/newsletter/unsubscribe/?email=alias@domain.tld
Example call via CMS Page:
{{block type="sota_newsletter_unsubscribe/unsubscribe" name="newsletter.unsubscribe" template="newsletter/unsubscribe.phtml"}}
Example call via Layout Update:
<block type="sota_newsletter_unsubscribe/unsubscribe" name="newsletter.unsubscribe" after="newsletter" template="newsletter/unsubscribe.phtml"/>
