Best Practices for Naming Templates

  • Keep names short and descriptive (under 50 characters).
  • Use prefixes by use case for easier management:
    • order_update_2024
    • promo_summer_sale
    • otp_login_flow
  • Avoid generic names like template1 — they make it harder to track usage later.

✨ Pro Tip: Treat template names as internal identifiers — customers won’t see them, but clear, consistent naming will save time for your team during approvals, audits, and reporting.
