Microcopy is the tiny words around forms, buttons, errors, and confirmations. It's easy to ignore. It's also where 90% of brands sound least like themselves.
You've probably hired a writer for the homepage. You probably haven't for the password-reset email. That's where brands sound the most robotic — and the gap is one of the easiest visible wins.
Rule 1: Match the moment
A successful checkout is a happy moment; a failed login isn't. The voice doesn't change. The tone does. "Welcome back!" is fine after login. "Welcome back!" after a failed payment is tone-deaf.
Rule 2: Avoid the four robot-words
"Please", "Enter", "Invalid", "Submit". These four words are 80% of bad microcopy. "Please enter a valid email" reads as an apologetic robot. "We need an email here so we can reply" reads as a human.
Rule 3: Make the button say what happens next
"Submit" tells the user nothing. "Send my brief" tells them. "Subscribe" is okay. "Get the weekly email" is better. The button is the last thing the user reads before deciding. Reward them with specificity.
Rule 4: Errors should be helpful, not just polite
"That email doesn't look right — typo?" beats "Invalid email format." It also reduces support tickets. Error messages are an opportunity, not just a notification.
Rule 5: Confirmations should feel earned
"Thanks!" is fine. "Done — we've got your brief and a real writer will reply by Tuesday" is much better. Confirmations are the last touchpoint before the user leaves; make them remember it.
A quick audit
Open your last sign-up email, your last error page, and your last contact-form confirmation. Read them as if you were a first-time customer. How many sound like the same brand that wrote your homepage? In most companies, the honest answer is "none of them". Fix the worst one this week.
