How would you reach out to YouTubers for promoting your product/service?

Hi all,

I'm looking to get my product promoted by YouTube influencers to reach more targeted users.

For example, I would like my app to get included in listing videos like "Top 10 apps for x" as well as in standalone product review videos.

What are some unique ways you have successfully reached out?

Do you entice them by sending the paid version of your product for free?

I want to learn about some creative ways to get their attention rather than sending a generic cold email.

Thank you 🙏
