This page will teach you how to use Postman through simple steps.
Choose the channel.
Once you've logged in and click on Create new campaign button, you will be prompted with the following screen to choose your channel and fill in a campaign name.
Postman is a multi-channel messaging service that allows you to send messages through 3 channels:
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.
Make sure there is a field called recipient that will contain the phone number or email address.
Phone number should be formated like 88888888 with no space, no dash, and no +65.
We do not remove duplicates for recipients in view of some use cases that require sending unique messages to the same individual multiple times. Scroll down to theRemove Duplicates in Excel sectionto find out how to remove duplicates in excel.
Step 3: Send Your campaign
You can test the message by sending it to your self and then go ahead and send your campaign.
