Based on our experience of customers using Voice SMS to contact their customers the following are our suggestions to ensure that your recipients understand and respond correctly to your voice SMS

Feel free to contact us to discuss this further if you need any further assistance, or have any additional requirements.

Test your message

  • Do a test message to check you are happy with the message before sending to a large number of customers

Message content

  • Remember to include your company name, preferably near the start so people will keep listening
  • Consider adding the name again at the end, as if your message is left on an answer machine then the start may not be recorded
  • Make the message as clear as possible remembering that the recipient might not be expecting a voice message.
  • Consider entering your message twice so they can capture any details on the repeat


  • Regulations mean that at numerical originator needs to be displayed for recipients, make this your business contact number, so if the recipient needs to call you back they can easily via their phone’s functions

Speed and Spelling

  • use additional punctuation to slow the message down, don’t worry about the message being grammatical english, think about how it will sound
  • if you need to spell a word out loud or give a reference number leave spaces between the characters ie “E X 0 0 7 7 6 0”
  • use audible words to add meaning, ie “ w w w dot esendex dot co dot uk”
