Here are some key metrics that you can use to measure and optimize the success of your outbound SMS campaigns:

• SMS delivery rate per message: Select Logs in the left-hand menu to view all sent messages.  You can also view the delivery rate for individual messages here.

• Click-through rate: If you used a shortened URL in your SMS, you can see the number of clicks received on that link by navigating to Tools -> Short links. Your click-through rate (CTR) is calculated by taking the number of clicks or messages delivered multiplied by 100. If the objective of your campaign was to drive your subscribers to a web page, the CTR indicates how successful the content of your message was in achieving that objective.
