24-Hour Messaging Window

WhatsApp enforces a 24-hour messaging window to ensure businesses only send relevant messages:

​
Within 24 Hours

When a customer messages you, you have 24 hours to respond with any type of message:
  • Free-form text messages
  • Media and documents
  • Interactive messages
  • Multiple messages allowed
  • No templates required

​
After 24 Hours

Once 24 hours pass, you can only send pre-approved templates:
  • Template messages only
  • Must be Meta-approved
  • Conversation charges apply
  • Starts new 24-hour window
  • No free-form messages

​
How It Works

  1. Customer sends you a message → 24-hour window opens
  2. You can respond freely with any message type for 24 hours
  3. Each message from the customer resets the 24-hour timer
  4. After 24 hours of silence, only templates can be sent
  5. Sending a template opens a new 24-hour window

​
Messaging Best Practices

  • Respond quickly - Aim to respond to customer messages within 5 minutes during business hours. Fast responses improve customer satisfaction and maintain high quality ratings.
  • Personalize messages - Use customer names and reference previous interactions. Personalized messages have higher engagement rates and reduce block/report incidents.
  • Keep messages concise - While you can send up to 4,096 characters, shorter messages (under 500 characters) are easier to read on mobile devices and get better response rates.
  • Use rich media wisely - Images and videos increase engagement but consume data. Optimize file sizes and only send media when it adds value to the conversation.
  • Avoid over-messaging - Don’t send multiple messages when one would suffice. Excessive messaging can lead to customer blocking and reduced quality ratings.
  • Respect opt-outs - Immediately stop messaging customers who opt out or request to stop receiving messages. Maintain an opt-out list and respect customer preferences.
  • Never send spam - Don’t send unsolicited promotional messages, chain messages, or content unrelated to your business. This violates WhatsApp policies and can result in number suspension.
