Hello,

you need to click at the verify link to verify your unsubscription:
<f:format.raw><f:uri.action pageUid="{unsubscribeVerifyUid}" extensionName="fpnewsletter" pluginName="pi1" controller="Log" action="verifyUnsubscribe" arguments="{uid: uid, hash: hash}" noCache="1" absolute="1" /></f:format.raw>

Best regards
