Common typos in the recipient field include spaces and symbols.
After you have sent the campaign, we will also provide the list of email addresses that bounced under statistics.
We only support Chrome, Firefox, Samsung Internet, the latest Microsoft Edge, and IE 11 at the moment.
If you are checking out PostmanSG, you can go through most of the steps before we ask you to enter a credential. This is so that the public officers can learn how to navigate the user interface first before initiating the necessary paperwork for procuring a Twilio account. Without the credentials, we are not able to send the SMS messages.
Before you send an SMS or Telegram message to citizens, you will be asked to enter your credentials and send a message to yourself to test the credentials. We recommend that you log onto Twilio console so that you can copy and paste in the credentials when prompted.
Subscription is currently not in the scope of PostmanSG. It will likely be part of other productivity products under OGP.
You can check the overall campaign sent status and timestamp on your PostmanSG dashboard after your SMS campaign has been sent. You can also download the delivery report, which provides more details on individual recipients' sent status and timestamps.
Alternatively, you can log in to your Twilio console and search for the relevant phone number. Your agency is the only one that can check through your Twilio account. We will not be able to access it.
We currently do not support WhatsApp broadcast message sending. WhatsApp costs more to maintain, especially if you don’t send enough messages regularly. If you do not track read receipts, SMS is the perfect alternative to notify citizens based on our user research. It is also much easier to set up a Twilio account than a WhatsApp business account. Detailed info on WhatsApp can be found on our Workplace group. Use your gov.sg email address to log in.
Messages sent to the public are usually governed by the communications teams within an agency. We recommend that you contact your communications team before setting up PostmanSG so that the agency is clear on what is sent to the citizens. You can create a common email account or mailing list so that your teammates can see what has been sent out to the public. PostmanSG is a productivity tool and we believe that the governance of the tool should fall under the purview of the agency.
PostmanSG does not bill the user separately. We believe in transparency in the pricing of our service. OGP will bear the cost of PostmanSG’s infrastructure, and at this point in time, the cost of sending emails. We ask the agencies to pay for the SMS message cost given that these are operational costs.
Depending on your usage, Twilio has a few different plans. If you do pay-as-you-go, you only need a corporate credit card on file. It works like a prepaid mobile plan. You top-up certain amounts of money every month and deplete the account as you send SMS. Post-paid mobile plans require you to contact Twilio’s rep and initiate a procurement process that adheres to IM8 guidelines. You can go to SMS & Twilio to find out more.
