The point here is to always end with something unique and relevant (or uniquely relevant) to your audience. Whether it’s a presentation, interview, webinar, or even an email. This part of the message gives your audience a sticking point, a bookmark to reference in the future.
“Hey, she was the girl that remembered that we had a big company 5-k coming up and ended her presentation with a slide of web sites for beginning runners.”
This serves as a great tool to show you know more about the company than its potential purchasing power and provides an excuse for you to check in from time to time.
Know your audience. End awesome.
