Use Uppercase Sparingly
Uppercase works for short labels, codes, buttons, and visual emphasis. It is usually harder to read when applied to full paragraphs.
Use Title Case for Headings
Title case is a strong default for article titles, product names, video titles, and landing page headings.
Use Sentence Case for Body Copy
Sentence case feels natural in emails, paragraphs, support replies, product descriptions, and long-form writing.
