Maybe it is just me but I find prelaunches annoying when prospective partners approach me to promote them.
When I am choosing to promote a product to my list, I am analyzing it in ways like these:
1. Is the product unique?
2. Is it a good offer?
3. Does it fit my audience?
4. Is the sales letter likely to convert well?
Most prelaunch pages just hint at some amazing system and don't tell me what the product will be about.
BEFORE I decide, I want to see the actual sales letter or at least a draft about it so that I know what I will be selling.
How else can I tell the quality of the offer and sales page and even if the product is of interest to my list?
