On Hold Messaging

Not sure about the efficacy of on hold messaging as a valuable addition to your marketing efforts?  For less than $100 you can run a test, a pilot, a trial, whatever you wish to call it.  Place messages containing calls to action in your next - or first - on hold messaging production; e.g., “Mention that you heard about the widgets while on hold and get 20% off your 2nd through 6th order” Or  “While you are on hold, go to www.widgets.com, click on _______ to get the secret code (no Captain Marvel secret decoder ring required), mention the code when we return to the line to be entered in our contest.”  You get the idea.
