-Scrape a good amount of active Youtuber users (you need the channel URLs)
– Get a t.co shortened link for your the URL you want to promote”
– Create a new Brand account / Channel called “Win a free Iphone 8 here: t.co/abc” (make sure you got the link in there!)
– Add all of the scraped users as channel moderator. Either manually (https://support.google.com/youtube/answer/7023301?hl=en) or using automation software, iMacro might work.
All users that you add as a moderator will receive an email like the one below. The beauty is, that Google makes the URL from your channel name clickable.
