What can PostmanSG do? 
Easily customize messages to reach a wide audience: Create a message template, upload a file containing customization parameters, and we will handle the rest for you.
Mass send emails: Just click send campaign and PostmanSG will send those messages out to your intended audience via email.

Is PostmanSG secure?
Email and SMS are not 100% secure. We recommend that you don’t put any sensitive information in the email or SMS content. Some of our users generate a recipient-specific unique link that opens up to a locked page. We have completed our VAPT on June 15th, 2020, and fixed our vulnerabilities. 
Can PostmanSG be accessed on the government intranet?
PostmanSG is only available on the internet at the moment.

Difference between the API vs User Interface Access
API calls: API stands for application programming interface. You need your engineers or IT support to help send your source database information to PostmanSG through an API call. In order to use this feature, you need to generate an API key from settings in the PostmanSG user interface and follow the Swagger Doc to start sending PostmanSG what you want to send through an API call.
User Interface: Users can access the user interface web app through https://postman.gov.sg. You can set your credentials for SMS under settings and start to send SMS and email campaigns right away.
