Guest Groups make it easy to create a new poll including the same group of guest you’ve invited before. You can store one Guest Group with the basic/free plan, but an unlimited number with a Premium membership.
Add the guests to the poll like you normally would.
Before you hit "Send", click on the "save this guest list as a guest group" link. The dialog that appears will ask you for a group name. Add a name and save. You have now saved your guest list as a guest group. Then hit "Send" to invite your guest to vote in the poll.
From the drop down options, select "Save Guests". A dialog will appear for you to add a name for your guest group. When ready, hit the "Save Group" button. All guests with an email address will be saved to the new group.
Save Guests will bring up a dialog so you can name the Guest Group.
All guests in the poll (provided they have an email address) will be saved to the new guest group.
When you are signed in you can navigate to your profile page from the top bar navigation menu
When the dialog appears, enter a name for the guest group and then the guests’ name and email. If you import your Google Contacts, start typing the name and you’ll see a drop-down where you can pick your contact. You can also copy/paste a list if you have one. After you’ve added your guests, hit "Save Group". You can add and remove guests from your guest group or delete your guest group at any time.
