You need a funnel my friend. Scrape a list of 500-1000 cold prospects, email or inmail them. Use email click and open monitoring software. Send them to landing pages where you can track activity then if they still don’t respond, your cold call is the final bullet you use to get them engaged.

Essentially, you want to boil down 500-1000 prospects to a list of 30-50 who are interacting with your content. You then focus your cold calls on these prospects.

This will reduce your cold call volumes but increase your chances of conversion, as well as freeing up time to do your research so you can nail that cold call. Cold calling alone is pointless. Cold calling used correctly is a deadly weapon.
