[Question]Monetize E-mail List With Low Number of Subscribers

So I have a growing email list using Seo-jacking and solo ads. This list is very targeted, and I have built an excellent relationship with each sub with auto responders. I am waiting until I have at a minimum of 1k+ subs before I start reviewing affiliate products and make some sales.

In what ways could I make some guap with my current list?

Would CPA offers work well, or would it look to much like spam?

Thanks guys!

If it's really really targeted to a micro niche, find offers that fit them, it will be alright. Or even better, create yours.

Pick a CPA trial product and write a whole mailer on it. The ingredients, the price, why they should buy it, etc and mail. It's all about making them feel like they need it. We have offers in pretty much every niche that people email daily.
