Dietary requirementsAllergies and needs the kitchen must plan for.
Your guest's nameOnly if the invitation includes a partner: it's needed for place cards.
Leave out
Arrival transport or parking questions: put that information in the invitation instead.
Sending it by email, text or WhatsApp, and tracking replies
Email: paste the wording into a new message, use the subject line above, and put guests in BCC if they don't all know each other.
Text or WhatsApp: use the short version. Send it to each guest, or to a group chat if everyone already knows each other, and pin it so the details are easy to find.
Tracking replies: for a handful of guests, a note on your phone works. For more, collect answers in one place, like a shared spreadsheet or a simple online form with the RSVP questions above.
