Do you any reference material I can read for writing cold emails and fine tuning the content? I have sent nearly 70 emails but so far I do not have a single response. May be my content is not powerful or emails are not reaching right audience.
It's incredibly hard to get 'qualitative' feedback. Cold emails, or phone calls work best. However, the best thing is to look at the data and if customers vote with their wallet or with their feet.
