To allow PushSend the ability to connect to your Google Analytics account, you’ll need to add your Google Analytics tracking ID to your landing page's Page Settings.
To get started, log in Google Analytics account to retrieve your Google Analytics UID. Click on the Admin tab at the top and make sure the correct Account and Property are selected. Then click on Tracking Info and select Tracking Code. You should see your Tracking ID. Copy that value down.
Once you have your Tracking ID, you can paste it into the Google Analytics ID Field under Tracking in your landing page's Page Settings. Make sure you paste in the entire value including the preceding UA.
