Of course, as Alain Mevellec points out, you are spreading your aim too wide. You are sending a ton of emails and I worry they aren’t personalized enough.
A 5% true connect rate — where they will take a call and do a demo — for a product no one has ever heard of, is pretty good.
It says to me outbound may work well for your product. If you can close any of these 5%, I say, outbound ftw here.
Many of your peers probably have a 0% connect rate, other than a Polite No, which doesn’t count.
