What to do when very different audience?

Hey all,
Thanks for reading. I'm starting to work on the sales page to one of my new products and would really appreciate your input since I don't want to alienate potential customers.

While creating this product, I realized that its premise appeals to two completely different crowds. One of the group is newly graduated women students, and the other is disapointed / failed marketers looking to try something different (which I assume is generally male).

I instinctively feel like "talking" to both groups, which have different goals and very different backgrounds, may dillute the copy's message. Each group might feel like I'm not addressing their specific need.

Am I wrong? Do you have any tip when dealing with a product who's potential clients have obvious different psychological buttons to push? (ie I found these women typically want to work and save up money for a house and stuff like that, very down to earth goals, while marketers usually look for get-rich quick easy money type stuff => the product allows both depending on how you use it, if you use shortcuts and have money to invest)

Just to make sure my question is understood properly, let me try to find a quick analogy.

Say you wrote a product called "How to Make Money Building Popsicle Castles". You determine that your main audience is popsicle fans, but it also appeals to stay-at-home moms.

If I address the copy very broadly, neither of the groups might feel like I'm talking to them. If I address popsicle fans (goal: build awesome popsicle castles oh em gee), stay-at-home moms (goal: make money to pay the bills) probably don't relate, and vice-versa.

Should I just write that the course was written specifically with both groups in mind, "here's what's in it for you"?

I tend to over-analyze everything so bear with me on this one, I'd love to hear your basic thoughts on the issue.

Thanks.
