Plan limit

I’m using the WhatsApp Trigger node on n8n Cloud.
The workflow runs correctly when I receive a new WhatsApp message — however, for each real incoming message, my execution counter increases by 4.

After checking the logs, it seems that n8n creates one execution for the actual incoming message, and three more for system notifications like “sent”, “delivered”, and “read” events from WhatsApp.

I’ve already added an IF node right after the trigger to filter out these system events (so the rest of the workflow doesn’t run), but the execution count still increases for every webhook event.

Is this expected behavior?
Is there any way to make n8n count only the real incoming messages (and ignore the “read/sent/delivered” status updates), so that my plan usage reflects actual user interactions?

Thanks a lot for your help and clarification!

Best,
