Keep it Simple: Focus on the core message of your email without any formatting or visual elements. Include Important Links: Ensure all critical links are included and are clearly labeled to guide the reader. Use Clear and Concise Language: The backup copy should be easy to read and understand. Mimic the Structure of HTML: While you can’t use images or buttons, you can mimic their structure by using text-based alternatives like dashes or asterisks for bullet points. Test Across Multiple Platforms: Ensure your backup copy is displayed correctly on various email clients and devices.
