Should your brand use exclamation marks?
Short answer: Probably not.
Long answer: Probably not, and here's why.

Clean, confident copy is one of the simplest ways to earn trust, and spelling is a foundational part of that. When your brand communication is polished, professional, and mistake-free, your audience pays attention to what you’re saying instead of getting distracted by how you said it.

Just because you know a big word, doesn’t mean you should use it. The most important thing you can do is ensure your audience understands you.

Give your brand permission to have a voice. And let that voice connect with real people in a real way.
