1. Visuals: Use images, colors, and fonts that align with your theme. 2. Tone and Voice: Ensure the language and tone match your brand and theme. 3. Content: The body of the email should support the theme with relevant information. 4. Call-to-Action (CTA): The CTA should be clear and relevant to the theme. 5. Layout: The overall design and structure should make it easy for the reader to follow the theme.
