Please: before you send somebody an email about bundling your product with theirs, do your homework. Look at that target product’s specifications. Look at how and where it sells. Go to the company website. Look for ways that your product can enhance their product. Figure out ways that both sides can win with what you’re suggesting.
Don’t waste your time or anybody else’s proposing useless bundles. I really hope that I never again have to look at a proposal from somebody suggesting that I take my content, that I own , and substitute that for their content, that they produced, instead.
In a way it’s like children. Yours may be brighter and better looking and more accomplished than mine, but I will still always like mine better.
