I've sent around 75 cold emails and I've received zero answers so far. I could try to send more of them but I think the response rate is already too low. Since this is not an already proved market where people are paying for this exact type of service, there is too much market risk to continue. I'll pivot to another idea... but which one?
For some reason, all the ideas that I had written down just a week ago seem way less promising now.
