Everyone you invited, in one place - who is coming, what they are eating, and who still owes you a reply
Every guest replies right on your site, event by event - the welcome drinks, the ceremony, the brunch - and picks their meal as they go. Set a reply-by date and replies close on it. You get an email the moment one lands
Add guests one at a time or paste a whole spreadsheet. Households stay together, and your list shows who is coming to each event, with the meal counts your caterer will ask for
Send one link and guests type in their own mailing address, so the invitations go out right. Need to nudge the stragglers or share a change of plan? Text the whole list from your guest list
Every gift is logged with who gave it, the note they left, and a tick for each thank-you card you have sent - so nobody gets missed and nobody gets two
