I look at this as less of “how much emotion” and more like “how much signal.” Projecting and integrating our authentic selves into business is no longer some "nice-to-have" marketing differentiator. Martech and AI have changed that. Today, giving something of ourselves into our value prop is a form of what evolutionary biologists call "costly signalling". By interjecting something about who we are into our customer-facing communication, buyers are reassured that there is a real human at work rather than a well-prompted facsimile. AI and martech has made any rational claim in a USP to be able to be copied instantly. But what can’t be cloned is the messy, specific, slightly idiosyncratic 'essence of human' behind it. How we express that will (and should) differ by type of business, category, customer expectation, and so on. The important point is not to bolt “personality” on as an afterthought, but to make it inseparable from the value we're seeking to create. If you're not sure whether your communication has enough 'you' in it, ask yourself: If a competitor could paste their name onto your USP, would the message still ring true? If yes, then it’s not personal enough. Sure, people buy from people. But more precisely: people use our personality as a shortcut to decide whether to trust our promises. (Sorry for the long answer. Once I get going, it's hard for me to STFU about these kinds of things!)
