Manually calling your customers one-at-a-time can be very costly and time consuming. When it's important to get an urgent message to all your customers fast, voice broadcasting service delivers your pre-recorded telephone message to 100s or 1,000s of your customers in a very short amount of time at a fraction of the cost. Mass automated phone calls, like manual calls, are either answered by a human or a machine.Learn more about voice broadcasting
Texting 100s or 1000s of your customers and employees one-by-one by copying and pasting the same text message over and over again can be monotonous and take hours. Alternatively, a bulk texting service delivers your personalized text message directly to mobile phones within a few minutes. Your recipients can reply directly to you as well.Learn more about sms broadcasting
