Here's the problem though: this assumes you have enough money in your marketing to buy those invitations to send out to a lot of people. Because you're sending one to each person, and because you'll probably need to remind them multiple times, that adds up to quite a bit of extra money on just the invitations.

If your marketing budget is already stretched thin and you're going to be spending plenty of cash just getting the event itself going, what exactly do you do to ensure you still have high turn out? The answer is label printing.

As soon as you know the date of the event get a large order of label printing done. Each label should mention the upcoming event and when it is. You might specifically have each label mention too that it's free to all, or at least indicate in some way that the person reading the label is welcome to come.

On all outgoing mail you need to put one of those labels on them. If you're inviting someone anyways than you probably have some kind of correspondence established with them. Just put a label on each of the things you send them. When going to places where you want to get out a lot of invitations just put a label on your business cards and then hand them around.

You will have already covered the cost of your business cards in your marketing so you still aren't having to spend any additional money. You can use these labels to try targeting a focused crowd of people, or you could try putting the labels on anything you send out period to draw in the biggest crowd possible.

The choice will obviously depend on how big you want your audience to be. You don't always have to spend a lot of money in order to boost up your attendance at various shows that you host. Find other creative ways of getting the word out without spending a lot of money.

Everything you do should be based on the knowledge that people are going to forget, and that they need multiple reminders in order to remember you. It doesn't matter if those reminders are printed invitations or labels you put on all of your marketing material. So long as you're reminding people you're increasing the odds of them coming and you're helping to make sure you have a nice, big audience at your events.
