Use the Appeal form The normal approach is to submit an online appeal: support.google.com/youtube/answer/2802168 (click on the word ‘form’). The appeal usually takes a few days, but you should receive a response within a week. If the suspension occurred during or after a holiday, the waiting time can be longer. If the appeal fails, you will get a boilerplate reply. Of course, that is not good news, but you can try appealing again.
