Getting folks to sign up for your email mailing list from your busy trade show booth can be a challenge. Here are a couple of options to make it easier on everyone.
1) Have folks send you a text message with their email address from their mobile phones as a request to subscribe. You can add this information to your list after the show.
2) Create a subscription form on your Web site, a page no wider than 600 pixels so it can easily be viewed on a mobile phone. Prospects with "smart" phones (i.e., Web access capability via their cellphones) who visit your booth can complete the sign-up process right away, filling out the subscription form from their mobile. This can save you a ton of work after the show.
TIP: no more than 10% of your business should be originating from any one source. Need new clients in 2010?
