I send out 2,000 texts 3X per week to my subscribers. If I send all 2000 at once, it alerts my cell phone carrier and has resulted in my account being blocked from texting for "abusing" their service. I suggest you implement a way to throttle back the speed of sending the texts so that we can decide whether 1 second, 2 seconds, 3, 4, 5, 6, 7 seconds between texts will bring "less attention" to the bulk texting activity.
