After you send a message through Givebacks you're able to view the recipient sent and open rates for each email and newsletter you send out. This information can be seen within Communications > View & Send Messages and Create Newsletters. The analytics provided are simply the number of contacts the message was sent to, the percentage of opens, and the percentage of clicks in the message. You can also see this information for text messages.
For Newsletters you can view the statistics for all your campaigns. Click View Campaigns. You will then be able to see all newsletters sent under that campaign.
