1. Choose the Right Category
Meta strictly enforces three categories: Utility, Authentication, and Marketing. Never submit a promotional message as a Utility template. If it contains any upsell or marketing material, it must be categorized as Marketing.
2. Avoid Open-Ended Variables
Templates with too many variables (like 'Hi {{1}}, {{2}}') often get rejected because they could be used to send anything. Always provide sample content for your variables when submitting the template to give reviewers context.
3. Formatting and Grammar
Meta rejects templates for poor grammar, spelling mistakes, or excessive use of emojis and capitalization. Keep your message professional, clear, and concise.
