My email is exactly like that. I tell the problem (possible problem), I tell them existing technologies ALL of them fall short because of 2 reasons (I explain), then I say how we solve the problem all together and ask for a quick webex demo of the platform. I reached out to CISOs and MDs and Directors....

Calls are tough, specially since I don't have their phone numbers and when you call some, mostly it goes to voicemail or they dont have time to talk.

I will try with followup, but I'm afraid of spamming their Inbox. How frequently I should send emails?

Don't cold call them. Set the calls up in the email and ask for 15-20 minutes. I would say twice a week. Probably 4-5 emails before you just say "It's clear my hypothesis is wrong. If things change I'll get back in touch".
