Counterintuitively, highly formatted and image-heavy emails can feel corporate and impersonal, decreasing engagement. Shifting to a simpler, plain-text style mimics a personal message from a friend, which increases perceived authenticity and encourages more replies and genuine connection.

OpenAI has publicly acknowledged that the em-dash has become a "neon sign" for AI-generated text. They are updating their model to use it more sparingly, highlighting the subtle cues that distinguish human from machine writing and the ongoing effort to make AI outputs more natural and less detectable.

Instead of using AI to generate generic text, leverage it as a partner to enhance your unique voice. A powerful technique is to have AI interview you to create a "story log"—a database of your personal anecdotes and experiences. This provides authentic, non-replicable material for future content.

In the age of AI, the new standard for value is the "GPT Test." If a person's public statements, writing, or ideas could have been generated by a large language model, they will fail to stand out. This places an immense premium on true originality, deep insight, and an authentic voice—the very things AI struggles to replicate.

As AI automates content creation, the ultimate differentiator becomes authentic human connection. This means prioritizing "reading the room," sharing personal stories, and even being inefficient to foster genuine relationships. While AI optimizes for output, marketers who optimize for humanity will build more resilient brands.

As AI generates endless look-alike content, a brand's ability to create genuine, human-to-human connection is a unique and defensible advantage. This 'vibe' cannot be automated or easily replicated, making it a crucial competitive differentiator in a crowded market.

To analyze brand alignment accurately, AI must be trained on a company's specific, proprietary brand content—its promise, intended expression, and examples. This builds a unique corpus of understanding, enabling the AI to identify subtle deviations from the desired brand voice, a task impossible with generic sentiment analysis.

Leverage AI in email marketing not to replace your voice, but to augment it. Use tools like ChatGPT as a brainstorming partner to generate angles and outlines. This frees up your creative energy to focus on infusing the content with personal stories and genuine connection that only a human can provide.

AI cannot replicate your lived experience, personal experiments, or unique perspective. To make your content "AI-proof," lead with your own stories, data, and case studies. Sharing screenshots, income reports, and personal struggles creates content that AI can't remix, making your voice irreplaceable.
