When you send messages via WAMA, they don't go out all at once. Instead, they enter a scheduling queue. Why? Because Meta's automated filters actively scan for high-speed robotic messaging patterns.
Here is how WAMA's native queue algorithm protects your connected numbers:
1. Randomized Human Delays
If you submit 100 messages to the /send-message.php endpoint simultaneously, WAMA saves them immediately and returns success IDs. However, the background dispatcher delivers them sequentially, injecting a randomized delay (between 6 to 9 seconds, averaging 7 seconds) between each message.
This mimicry of human typing behavior prevents spam triggers that look like instant, automated blasts.
2. Rate Limiting by Instance
Each connected instance has its own separate dispatcher thread. If you connect 5 numbers, they send messages completely in parallel, but each individual thread maintains its own safety delay. This isolation prevents one busy number from blocking the queue of another.
3. Dynamic Interval Adjustments
For high-volume Enterprise plans, the queue interval dynamically optimizes based on the total queue depth and instance age. Newly linked WhatsApp numbers are warmed up slowly, starting with longer safety intervals, which gradually decrease as the number establishes sending history.
