Why Choose a Mass Calling and Texting Service?

If you are still relying on only mail or even email to get your message out, chances are your message isn’t being received or read in a timely manner. A mass calling and texting service allows you to get your message into your contact’s hands in minutes. Also, a mass calling service like One Call Now, provides reports so you can be sure your message was received and heard.

Here are some statistics that can’t be ignored:

  • 95% of Americans own a cell phone, and 77% of those are smart phones.
  • 97% of American adults text weekly.
  • On average, Americans text twice as much as they call.
  • Texts have a 99% open rate.
  • 95% of texts will be read within 3 minutes of being sent.

Mass Texting

Quickly sending tens or hundreds of text messages is a hassle. Yet, texting is one of the most effective ways of ensuring a message is seen. Fortunately, mass texting with One Call Now is simple and fast. What’s more, your text message can also be broadcast as an email and phone call, ensuring even greater coverage. All this from the same simple interface or our mass calling app. Like calling, mass texting enables you to create one message and quickly send it via SMS text to a list of contacts, in multiple languages if required. The critical difference between regular text messaging and a mass texting service? The ability to save common messages, insert custom text into each message, and easily define delivery groups.

Mass Messaging

Mass messaging broadcasts a pre-recorded message to a list of contacts without the need to manually dial each number. One Call Now’s mass messaging platform makes it easy to broadcast messages via mass calling, mass texting, and mass email from a computer, tablet, your phone, or an app. One Call Now delivers these messages within minutes, and also provides the ability to deliver a customized message if the call reaches voicemail.
