🚫 WhatsApp Limitations to Be Aware Of

Though WhatsApp is a high-engagement platform, it enforces some strict limitations:

  • 24-Hour Customer Window: You may send any message within 24 hours of a user’s last message. After that, only approved templates are allowed.
  • Template Review Process: Templates must be clear, relevant, and professional to pass WhatsApp’s review.
  • No Cold Messaging: You may not message users who haven’t opted in.
  • Content Restrictions: Prohibited content includes gambling, adult products, tobacco, alcohol, and some financial services.
  • Number Quality Monitoring: High block/report rates can reduce your sending limits or suspend your account.

🚨 Failure to comply can result in restrictions, warnings, or account bans.


🕐 Understanding WhatsApp’s 24-Hour Messaging Rule

One of WhatsApp’s most important rules:

  • What is it?
    You may send free-form messages to users within 24 hours of their last message.
  • How is it reset?
    Each new message from a user resets the 24-hour timer.
  • What happens after 24 hours?
    You can only send pre-approved message templates outside the 24-hour window.
  • Why it exists?
    To prevent spam and protect the user experience.

🔁 Acele automatically tracks each user’s 24-hour window and ensures compliant message delivery.


💬 What Are WhatsApp Template Messages?

Used when the 24-hour window has expired, template messages help you continue communication.

  • Definition:
    Pre-approved message formats for notifications, reminders, and promotions.
  • Common Types:
    • Transactional: Order updates, appointment reminders.
    • Promotional: Sales, discount offers, product launches.
    • Account Alerts: Login alerts, password resets.
  • Best Practices:
    • Use clear and personalized language.
    • Avoid spammy or aggressive language.
    • Include dynamic variables (e.g., name, order ID).
    • Ensure your message adds value.
  • Approval:
    All templates must be reviewed and approved by WhatsApp.
  • Cost:
    WhatsApp charges per conversation when templates are used.

💡 With Acele, creating, submitting, and managing templates is streamlined inside the dashboard.
