The status of each message can be seen on the dashboard on the landing page after login. Refer to the Postman Guides for detailed information about status tracking and reporting features.

Q3: What should I do if messages aren't being delivered?

Check these common issues:

Verify recipient contact details are correct
Check campaign status in dashboard
Verify message content follows guidelines
Contact Postman Team if issues persist

Large Campaign Management

Q4: What are considered large or time-sensitive campaigns?

Campaigns that fulfil at least one of the following:

Time-sensitive: If you are making >50 API requests per second, or >100 message segments per second;
Large campaigns i.e., above 200,000 recipients

Q5: How will other users’ large campaigns affect my campaign?

Both your single send and batch send messages may be delayed during periods of high system load. If you have a non-critical campaign planned, consider shifting it to a different date/time slot for best deliverability results.

Q6: Will Campaign Creators be given advance notice of upcoming large campaigns?

Yes, the Postman Team will strive to inform you two weeks in advance via email.

Q7: What should an existing Campaign Creator do if he/she has an upcoming large campaign?

An existing Campaign Creator should give at least two weeks’ advance notice before the campaign start date by:

Completing and submitting the large time sensitive campaign template to SDD at mindef_postman_pic@defence.gov.sg for our tracking as MINDEF/SAF Postman PIC (Person-in-Charge).
Registering their use case through the GovTech registration form.

Q8: What should a new Campaign Creator do if he/she has an upcoming large campaign?

A new Campaign Creator should register his/her use case with Service Delivery Division (SDD) at mindef_postman_pic@defence.gov.sg. An officer from SDD will get in touch with him/her to gather more information and provide guidance.
