Message Templates & The 24-Hour Customer Service Window
Master Meta's Highly Structured Message (HSM) template approval process, 24-hour service session rules, and direct wholesale billing.
Message Templates & The 24-Hour Customer Service Window
Meta enforces specific messaging policies to prevent spam and ensure high engagement on WhatsApp. Understanding how Message Templates and the 24-Hour Customer Service Window work is essential for successful marketing broadcasts and live agent support.
1. The 24-Hour Customer Service Window
When an end-user sends a message to your business WhatsApp number:
- A 24-Hour Customer Service Session opens immediately.
- During this 24-hour window, your team can send free-form text, images, voice notes, PDFs, and links to the customer.
- No template pre-approval is required for messages sent inside the window.
- Replies inside the 24-hour window incur zero Meta delivery fees.
What Happens When the 24h Window Closes?
Once 24 hours have elapsed without a reply from the customer, you cannot send free-form text messages. To re-engage the customer, you must use a Meta-Approved Message Template.
2. Meta-Approved Message Templates (HSM)
Message Templates are pre-approved message formats required whenever:
- You initiate an outbound conversation with a contact who hasn't messaged you recently.
- You run a scheduled bulk broadcast or automated follow-up sequence.
- You follow up with a lead after their 24-hour customer service session has expired.
Template Categories
- MARKETING: Promotional offers, product updates, newsletters, discount codes, and abandoned cart reminders.
- UTILITY: Order confirmations, appointment reminders, shipping tracking, billing notifications.
- AUTHENTICATION: One-time passwords (OTP) and two-factor verification codes.
Variable Parameters
Templates support dynamic parameters like {{1}}, {{2}}. For example:
*"Hi {{1}}, your order #{{2}} has been confirmed and will ship within 24 hours."*
When launching a broadcast or sending a direct message in MANZA, our template engine automatically populates {{1}} with the contact's name and other CRM custom variables.
3. Creating Templates Inside MANZA
- Go to WhatsApp Hub > Message Templates (
/app/whatsapp/templates). - Click "+ Create New Template".
- Configure:
- Template Name: Alphanumeric and underscores only (e.g.,
lead_followup_offer). - Category:
MARKETINGorUTILITY. - Body Text: Type your message and use the variable inserter for dynamic tags.
- Buttons: Optional Quick Reply buttons or Call-to-Action URLs.
- Click "Submit to Meta for Approval". Meta typically reviews and approves templates within 2 to 15 minutes.
4. Wholesale Pass-Through Billing (Zero Markup)
Unlike traditional Business Solution Providers (Wati, Interakt, AiSensy) who charge ₹1.10–₹1.35 per message with wallet locks, MANZA connects directly to your Meta Cloud API account:
- Meta bills your linked payment card directly at wholesale rates (~₹0.86/marketing message in India).
- MANZA charges a 0% message markup.
- Free customer service replies inside the 24h window remain 100% free.
