I developed a unique software that solves a particular problem. There is interest in the product and sales are ok. But when I approached (at least 10) gurus who speak or write about that topic, offering an affiliate link or just for their opinion. Not one responded. So i am thinking that my email must be wrong or there must be is a specific way to approach them.
I'm an "influencer" some would say and we get emails all the time. The only ones I've ever worked with when being pitched is ones who knew what I would and would not be involved with, personalized their approach and didn't write a cheesy template email like the Jennifer Lawrence ones.
