How can I see who has accepted an Invite and who has declined?

For a quick overview, go to Status. The left hand column gives you all your key guest stats:

For more detail, go to Guest List. When you first load the page, the main table displays everyone who confirmed (via invite or your Registration Page), declined (via invite), or who has been waitlisted. All Confirmed guest rows are green, all Declined guest rows are red and all Waitlisted guest rows are blue.

To additionally see bounced guests as well as all invited guests who have not yet responded, click on the Filter icon and select “View All Invited”.

Any bounced invites are also marked as yellow rows, with an explanation of the type of bounce viewable by mousing over the status button in their row. Further detail on the bounce reason is available by clicking the status button.

You can filter guests by their current RSVP status using the Status Filter dropdown (as in above image) or by how they registered, using the Registration Filter dropdowns (image below).
