To clarify, your channel Monetization is not related to how you promote your videos on YouTube. Learn more about YouTube Partner Program policies here: https://goo.gl/jUS9JV . Hope this helps.
The best place to check is your Monetization page in Creator Studio: https://goo.gl/1cosBi . From there, you’ll see an explanation with links to relevant resources. You’ll also see the option to reapply from that page in 30 days. Thanks.
