I will give you an iMacro script for Unsubscribing from Youtube channels. With this script you will be able to easily and on autopilot unsubscribe from all the channels you have subscribed to. The script was created by me, so I guarantee it works great. By purchasing this offer you will get the Youtube Unsubscribe iMacro script and a word file that describes how to install and use everything. If you have any questions, let me know.
Script updated and working well into 2019!
