I have emails...what can i do to monetize?

I am pretty dumb to IM, i have been apart of the site for a Long while. I picked up a few methods but I always get discourage and can never stick to one thing. Im guilty of it.

However, I have an email list. What can be done?

Whateverrrr you want

How many emails and what is the niche?

The niche is "how to make money" and I get about 10 emails a day
