Which is the best way to tell people we are exhibiting?

The only honest answer to that question is “it depends”. So the best advice is to take no chances. Use all the available channels: ask easyFairs to put information about your presence on the show website, use your direct mail lists, place a show banner on your website, mention your participation in advertising (if you have already planned advertising, there’s no added cost apart from a small artwork change). And one of the best ways is still word of mouth. Get your sales reps and other customer-facing staff to mention your participation.
