For the most part, these techniques have gone the way of the dodo. As a reference point, this Harvard Business Review article cites a report from over a decade ago pointing out that 90% of people weren’t responding to cold emails even then.
But that’s not to say that outbound sales are dead. Outbound reps can still connect with a target audience or a specific market segment. They can still effectively sell products — but spammy sales tactics won’t get the job done.
Instead, reps need to build rapport, focus on relationships, and choose their moments carefully. In other words, it’s not about how many messages and voicemails you leave; it’s about making sure that you’re addressing pain points and helping the prospect better understand how your product or service solves their needs.
