A single invitation is a flat fee, not a charge per guest. Once it is made, share it with your whole guest list for free. You can add event details such as date, time and venue directly on the card.
A single invitation is not tracked: recipients reply to you directly (by email or message), so there is no guest list to manage. If you want to see who is coming in one place, our Events product adds a live guest list and RSVP tracking on top of your invitation.
See the events page for guest lists and RSVP tracking.
