Whether you have a really clear idea of what kind of event you're having or not, you can usually start creating buzz by making the upcoming party look really inviting so people will want to be there and will RSVP "yes." Using social media such as Twitter and Facebook, as well as your company Web site or personal blog, can get people talking and even can replace costly and time-consuming paper invite mailings. Rolling out an event by posting a date and time, following with another status update with a catchy name or hint about the venue and finishing with a posting with the details of the event itself is one way to build up and keep reminders coming without paying for multiple cards and postcards. It's also greener by saving on paper and printing resources.
Making the RSVP process easy for invitees will help you stay on track and on budget, and an option to toggle a simple yes or no without having to explain the why of whether someone will attend makes it even easier on guests. It might be worth it to invite some special guests, like the media and VIP clients mentioned earlier, with a more personal touch such as a follow-up phone call or hand-written note on stationery. Also, have a plan for following up with all partygoers by updating social media or sending thank you's electronically or on recycled paper after the event.
