All of the mobile messages stats you need to measure the response to your message are available on your mobile message manage page. Overall statistics are tracked in the "Statistics" tab. Clicks on individual links in your message are tracked in the "Clicks" tab. And if you've set up a body test, overall statistics for each subject line are tracked in the "Test Results" tab.
In the "Statistics" tab, we track total sent, we track total clicks, click rate (total clicks divided by total sent, as a percentage). We track action rates if you link to an Action Network page or embedded widget, including total actions, action rate (total actions divided by total sent, as a percentage), and actions/click ratio (total actions divided by total unique clicks, as a percentage). We track donation statistics if you linked to an Action Network fundraising page or an ActBlue fundraising page. We'll track donation rate, total donations, donations/click ratio, average donation amount, and total amount donated. Finally, we track total bounces and bounce rate.
The ratio numbers are particularly useful, as they give you an opportunity to get a handle on how your message is performing quickly, especially in relation to another message test. While your click and action rates will increase over time as more activists engage with your mobile message (starting at 0%, then 1%, then 2%), the ratios should stay roughly the same (20% clicks/action, even though total clicks and total actions are both increasing). So you can make a judgement about how well a message is doing quickly, as those ratios should stay similar over time once they reach a point of stability.
Note: Bouncing mobile numbers are also automatically unsubscribed from your list. More here.
We also track clicks on each individual link in your message in the "Clicks" tab. There you'll see a list of all the links in your message, arranged in the order they appear in your message. We track both the unique number of clicks (so, if an activist clicks twice on that specific link, they will only show up as one in the unique clicks column) as well as the raw number of clicks (where they will show up twice).
If you've set up a body test, you'll see a "Test Results" tab listing each body test and the statistics for it. You can choose your winning message by clicking the "Duplicate" button next to the one you want, setting up a message with only that subject, from line, or email body. Don't forget to exclude your test message when you send the winning version, to ensure nobody receives a message twice!
Or you can use the "Duplicate With Exclude" button, which will duplicate the message with the body test you picked, exclude the first message from the duplicate, and remove the random limit, getting you ready to send the winner without having to worry about targeting!
