This page will teach you how to use Postman.

Choose the channel that fits your purpose.

Postman is a multi-channel messaging service that allows you to send messages through 2 channels:

However, do not that each channel has its own setup so do navigate to the specific section to find out more.

Campaign name is simply for your own record purposes, it does not appear in the email you send to the public.

Once you've chosen your channel, please follow the following steps:

Step 1: Create a message template

Postman allows you to control how much each message is personalised. Message templates can be used in a few ways:

Message Template

Use Cases

No {{ }}

Generic message for everyone

Mostly standardised content with a few keywords like {{name}} {{item}} for fields that are relevant

Appointment reminder


Unique message for everyone.

Postman has implemented a universal footer for all email campaigns in order to comply with Singapore's Spam Control Act and align with international bulk email practices (CAN-SPAM Act or EU’s ePrivacy Directive). Please go to our unsubscribe page to learn more about this feature.

Step 2: Set up a contact list in CSV format

Most of our users have an internal database that includes all of their contacts. You can export the contact list in a CSV file. If you are not sure what to include in your CSV file, you can Download a sample .csv file in the step for uploading the recipient list in CSV format.

Note the following points to ensure that the details in your CSV file are correctly displayed in your email:

  • Make sure there is a field called recipient that will contain the phone number or email address.

  • Make sure the headers are in lowercase.

  • Your email should be formatted like abc@gmail.com.

  • Phone number should be formatted like 88888888 with no space, no dash, and no +65.

Take note to remove recipients who previously requested to unsubscribe from your communications.

Step 3: Send your campaign

You can test the message by sending it to yourself. When you are satisfied with it, go ahead and send your campaign.
