⚡Quick answer -

You can, but not recommended.
Each WhatsApp template must serve one clear purpose—either:

• Utility (Transactional)
• Authentication
• Marketing (Promotional)

This classification is required by Meta’s official categories. Mixing purposes in one template can cause approval delays and rejections (if misused). Such templates (if template content follows the Meta's guidelines) will always be a part of the Marketing Category, even if they contain a notification.

Why Categorisation Matters?

Meta uses template categories to:

• Ensure compliance with WhatsApp Business policies
• Enforce rules about when messages can be sent (e.g., outside the 24-hour service window)
• Apply stricter reviews to promotional content

Once submitted, Meta may approve, reject, or recategorize your template. This affects delivery, opt-in requirements, and campaign success.

Risks of Mixing Purposes

If you submit a template labelled as Utility but it contains promotional wording (e.g., “limited-time offer”), Meta may:

• Reject the template for mislabelling
• Recategorize it as Marketing without notice
• Delay approval or flag it during audits

Examples: Correct vs. Incorrect Categorisation

Best Practice

Always create separate templates for different goals:

• Utility → transactional updates (order shipped, payment confirmed)
• Authentication → login/OTP messages
• Marketing → promotions, offers, re-engagement

This ensures faster approvals, fewer rejections, and higher delivery success.

✨ Pro Tip: Before submission, do a quick “intent check” — If it has any salesy or discount language, mark it as Marketing!
