Send a unique confirmation email for each show
Imagine the following scenario: Body Worlds is coming to town and you will be hosting their exhibit for a while. There is a movie theater nearby that is hoping to capitalize on the interest this exhibit will generate and has decided to show a second run of Casino Royale, which features a scene at a Body Worlds exhibit. The theater owner calls to discuss cross-promotion and he wants you to advertise his theater during this run in return for a sum of money. Obviously there are opportunities for you to put advertising on ticket or receipt stock, but that only works for walk-up sales. What about people who are buying tickets online? With one of the features in PEO, that's no problem.
There has always been the ability to have promotional material on your PEO confirmation emails, but it was generic; everyone received the same email. As of version 3.2.5, you can take advantage of the ability to have a unique confirmation email for any show you would like. You can put an ad for the movie theater on the confirmation email for patrons who purchase Body Worlds, and do something totally different for those who are buying a different show. When creating your confirmation email simply choose the show you would like to associate it with using the Show drop-down, and then continue designing the email normally.
Keep in mind that a show-specific email is only sent to patrons who purchase that show exclusively; otherwise they receive the generic email. If you wanted to take it a step farther and you're using Print at Home, you can get around this by putting the promotional material on each Print at Home ticket (but that's another post for another day).
I hope this scenario gave you some good ideas to get creative with your emails and unlock a little bit more of the potential of PEO. Are you currently using this feature on your site? Have you had experience with advertising opportunities using confirmation emails or Print at Home tickets? Leave a message in the comments.
