  • Check the message status in the Schedules view
  • Ensure the contact is subscribed (status: active)
  • Double-check your API key and secret
  • Ensure your provider account is active and has sending credits
  • Verify the phone number is registered with your provider
  • Contacts who reply STOP are automatically unsubscribed
  • Check the contact’s subscription status in the Contacts view
  • Re-subscribe the contact if this was a test number
