The campaign dashboard shows you all the campaigns that you have sent in the past.

You can click into your campaign to see the breakdown of the summary stats.

You can also download the campaign delivery report, which gives you a more detailed view on the status of each recipient number.

Types of Status for SMS

SMS campaigns would generate two types of status:

  1. SENT: Your SMS was successfully delivered to the recipient.

  2. ERROR: The mobile number was not valid. See error code descriptions for more details.

Unlike emails, you generally would not have any INVALID status. To see the entire list of SMS errors, you need to click on the Export button on the campaign landing page.

Twilio Sending Status

Twilio has received your request to create the message. All new messages sent from a specific Twilio phone number are created with a status of queued.

Action: Wait

*If the message has been stuck in the queue state for > 2 hours, please email postman@open.gov.sg for additional assistance.

Twilio is in the process of sending the message. This status is usually only present for a very short time.

It is important to note for this that the status reflected here is what Postman receives from . There might be instances where the status reflects "SENT" but a recipient may not have received the message. This could be because the telco has not successfully delivered the message to the recipient. If the recipient has received the message, the status should reflect "DELIVERED".

If you are facing such a situation, you can find out more about the status of a particular message by logging into your Twilio messaging dashboard. Twilio explains the error codes .
