Copy, or written text, is 100% necessary for any business.
But, not all copy is good. It's often sterile. Or not enough. Or too much (Insert the Goldilocks and the 3 Bears analogy here).
The goal of creating copy is to meet your objective but do it in a way that gives your audience an experience of your brand.
And that's not always easy. But, people want to invest in people, not just a business.
To humanize your brand, you need copy that connects.
