What Guidelines/Best Practices Should I Follow When Sending SMS Messages?

  • Do not send unsolicited SMS messages. Make sure you have recepients' permission before sending marketing SMS messages.
  • Send an SMS approximately every 3 months to remind contacts that they are still opted-in.
  • Provide a clear and easy way for people to opt-out from receiving SMS messages from you.
    Note:
    • We automatically append Txt STOP to <XXXXX> to end, HELP for info. <XX>msg/mo. Msg&Data rates may apply. to all SMS confirmation messages.
    • Any time an SMS call-to-action is used (e.g. Text Helptest to 33233 to receive a coupon), you must clearly display the following terms of service/conditions text:
      
      Message & Data Rates May Apply. Text STOP to end. Ts&Cs: bronto.com/sms							
      This includes SMS calls-to-action in emails, tweets, Facebook posts, webforms, webpages, and any form of print communication.
  • Do not put false or misleading content in the body of your SMS message.
  • Create an extended welcome series. In your workflow, set up a delay between the opt-in trigger and the follow-up message.
  • Consider the time of day that you want to send based on the amount of contacts you have. The throughput for sending SMS messages through a short code is approximately 100 messages per second.
  • If you use Data Loader to suscribe contacts to an SMS Keyword, and you are subscribing a large number of contacts, a contact may opt-out before the process completes. To avoid sending messages to contacts that have opted-out, upload contacts in small increments.
