WhatsApp error 4 Sending paused — the app hit its rate limit
Transient — may succeed on retry
LetsBot-side
Rate and sending-limit errors
Short answer
Your message was not sent because the app that connects your account to WhatsApp reached the limit Meta sets on how many requests it may make in a period. The limit is on how often requests are made, not on the content of your message, so sending again later can work.

How to fix it
- Wait a while, then send the message again.
- If it keeps happening, contact support — this limit belongs to the app that connects your account to WhatsApp, not to your own account settings, so LetsBot is the side that checks it and reduces how many requests the app sends.
