How to Film a Collab with a Famous YouTuber?

[MiNsHi]

They usually have their contact information in their description box or channel. You can contact them through there.

You can also inbox them on YouTube, but I'm not entirely sure if they all check their inboxes.

ALSO, you can contact someone through twitter.
I know that jacksgap (probably the most famous vlogger on youtube) is always in twitter, and is always ready to help someone when they need it. They can also give you tips on how to get fans on YouTube, and they do a lot of collabs. You can contact them through twitter. Their information is always in their descriptions.

You might not be able to start off collabing with extremely famous people immediately. You might want to start off with some other people like Jeydon Wale, Connor Franta, Oli White, Sam Pepper, or Caspar Lee.

Good luck!
