If you just need an idea of who has seen the announcement you have posted, clicking in the upper right of the announcement on view report will bring up a list of all of your members and when or if they have viewed the announcement. This will show the date they viewed the announcement whether they logged in to Unison.io or opened the email notification. 

Clicking the announcement icon in the upper right of this screen will allow you to send a follow up email or text message announcement to the relevant members based on their status.

To view and manage responses for individual action items on an announcement, open the announcement, and then click Manage responses to the right of any action item. Here you will see a list of all of your members and if they have responded to the action item or not.

Complete an item for a member in the response column, or mark an item complete without actually completing it by checking in the Status column next to their name.

You will also find some additional helpful tools in this area: 

Each action item has an icon of an envelope in the upper right corner that will allow you to email all members who have not yet responded to this action item. Doing so can help you send out a quick reminder to anyone who has not completed the item asking them to do so. 

RSVPs and polls have the additional option to email everyone with a specific response so that you can follow up with those who have responded in a particular way. 

When collecting form answers from your group, all responses can be downloaded by clicking the icon of the Cloud with a down arrow in the upper right corner. Doing so will download forms as a .csv in spreadsheet form. Individual documents can also be viewed by clicking on the blue text under the Response column in this pop-up.
