All Contacts are Not Customers

 Cross Promotion

Consider creating a list of strategic partners that will not necessarily attend your trade show, but will assist you in promoting it.  For example, ABC Association cannot share emails with you, but is able to send out a blast to their contacts at no charge to you. And you in return for them. 

 
Your staff may be able to provides names you never thought of.
Contact Ruth Failer for other ways to promote your trade show attendance.
