What is Postman SMS?

ALL Singapore government agencies must use Postman to send out SMSes using the “gov.sg” sender ID while disseminating official communications to the public. Agency CIOs will be notified of any non-compliance.

Postman SMS (also known as Postman v2) is a secure messaging platform developed by Open Government Products that enables government agencies to send mass, personalised communications to the public through SMS.
