Delivery timing

Messages are queued, never sent instantly. Each device sends with a 15-45 second gap, pauses after every 50 messages, sends only between 9am and 9pm, and stops at its daily warm-up limit. A new number starts at 20 messages a day and ramps up over about a month. These limits are what keep your number from being banned, so they cannot be turned off.
