On X you share a short post with an image and the link. That works best for public events, like an open day, a launch or a club party.
If you leave out the image, X often shows a card with the link preview itself.
Still weeks to go? Pin the post to the top of your profile so new visitors see it straight away. A short reminder with the same link a week before does the rest.
Next step: Sharing via Signal, Telegram or text message
