Three things to keep in mind when you are writing a marketing message.
The other person does not know. Even when they share your same background, even when they face similar challenges, even when they have already tried similar products, even when your name is known and celebrated. Who reads does not know what you mean, what you care about, why you are good for them, why you are interrupting their day, and a whole lot more. And if they are left doing the effort to figure that out, they are gone.
The other person does not care. You might have the most brilliant invention of the past two decades, a flawless and unmatched technology, a fantastic company culture, and the most talented people working in each of your teams. Who reads cares literally zero about all of this, they have their own inventions, technology, culture, people and agenda. And if they are left building the bridge on their own, they won’t even start.
The other person is a human being. When you enter a room full of people, you most likely will not talk about “future-proofing”, “streamlining”, “best-of-breed”, “capabilities”, “artificial intelligence”, and so on. The mind of who reads gets fuzzy when they are faced with inflated jargon, they stop focusing on the message and they start thinking about what they should do instead. And if those are the words you are building your message around, they will find someone who treats them as a person.
Of course, the most important thing to remember is the fact that you are the first reader of your marketing messages. If something does not sound right, if something is unclear, if what you are producing is not what you would read in your own time, reasearching a product, seeking a solution to a problem. Then others will probably not find it more compelling.
