If You're Looking to Sell Me Something, Please Spare My Inbox. Call Me Instead

Steven Broudy, a senior sales leader posted on LinkedIn telling sales reps to step up and use the phone instead of spamming him with what we all know are automated emails. I didn't say it, he did. Mr. Broudy caused quite a stir with his post, but is it true? Should sales reps really use that ugly thing we call the phone?
