Did you know that Call-Em-All broadcasts 2500 calls per minute? Since most numbers are called within seconds, responses can be overwhelming. Hearing from your recipients can be a good thing, but sometimes you may want a little more manageable response rate.
You can slow down the call speed by going to My Account-->Update under Preferences.
Call-Em-All's automated messaging service allows you to send a voice broadcast, group text, or both to every phone number on your list. Clients include Amazon, Siemens, BBB, YMCA, San Antonio Spurs, Avon, and Syracuse University.
