Sendmize Guide: Mastering the 24-Hour Rule on WhatsApp & Messenger (Without the Headaches)
In today’s world of instant replies and smart automation, messaging platforms like WhatsApp and Facebook Messenger are powerful tools for businesses. But there’s one rule every business needs to understand and follow: the 24-hour rule.
In this quick and practical guide, we’ll break down what it means, why it matters, and how Sendmize makes it ridiculously easy to stay compliant—while still keeping conversations flowing with your customers.
🚨 What is the 24-Hour Rule?
The 24-hour rule is a messaging policy from platforms like WhatsApp and Messenger. It defines a 24-hour window after a user interacts with your business (sends a message, taps a button, etc.), where you can freely send regular, non-template messages.
Once that time is up? You’ll need to switch to approved message templates (on WhatsApp) or sponsored messages (on Facebook) to reach back out.
✅ Key Things to Know:
-
The 24-hour countdown starts as soon as the user engages (e.g., sends a message, clicks a CTA).
-
Inside this window, you can send conversational, promotional, or transactional messages.
-
After 24 hours, free-form messages are blocked—only WhatsApp templates or Facebook paid messages are allowed.
-
Sendmize helps you automate all of this, so you never have to worry about missing the deadline.
🛡 Why the 24-Hour Rule Exists
-
Protects Privacy: It keeps users from being spammed or overwhelmed.
-
Encourages Timely Replies: Businesses are rewarded for being responsive.
-
Aligns with Privacy Laws: Think GDPR and similar global policies.
😬 What Happens After 24 Hours?
Your message freedom ends—but it’s not the end of the conversation. Here’s how to continue engaging your audience:
1. WhatsApp Template Messages
-
Pre-approved by WhatsApp for things like order updates, payment reminders, or support follow-ups.
-
Dynamic placeholders allow personal touches. Example:
“Hi {{name}}, your order #{{order_id}} has been shipped!”
With Sendmize, creating and sending these is a breeze.
2. Facebook Sponsored Messages
-
For Messenger users, you can re-engage with paid messages.
-
Ideal for retargeting offers or promotions.
