Just out today is MarketingSherpa’s 2006 Marketing Wisdom report. It’s a great example of using your customers to create content for you. The Sherpa folks sent out a survey link in December asking the 100,000-plus readers of their email newsletters to submit a lesson learned or useful anecdote from 2005. The results – from 110 readers – are compiled in a nifty looking PDF report.

Also clever, the report has an upscale sponsor, search marketing firm Omniture. This kind of “free” download is a win-win all around. Passalong or word-of-mouth marketing for Sherpa, in addition to sponsorship revenue. The glory of being published if you’re one of the contributors.

The readers who contributed are from small companies and big, including American Red Cross, CompUSA and The Motley Fool. Entries cover everything from email and search engine marketing to growing and managing clients if you’re a consultant or agency.

P.S. You’ll see an entry from yours truly on page 19 about RSS vs. email as a channel to reach your audience.
