Wedding invitation wording that guests can act on
Start with the guest's name, then the couple's names. A line such as "Amara and David invite you to their wedding" is enough. You do not need a poem. Guests are looking for whether this message is for them.
Put the date, the start time, and the place in the next lines. If the ceremony and the reception are in different rooms, say both. If the weekend has a Friday dinner and a Sunday lunch, name the event this person is invited to. One message that says "the wedding" is vague when your family has three gatherings.
End with the reply. A personal link is clearer than "text me back". The guest opens the site, sees the schedule, and answers for that event. Ask for a meal or a song only if you will use the answer.
Write the way you speak. "We would be glad to have you there" is warmer than a template that could belong to anyone. Keep the same sentences for WhatsApp and email so an aunt who gets both does not think they are two different days.
When you need the reply itself, the RSVP wording templates include WhatsApp messages in English and in French, ready to copy.
