I use a promotional calendar and have a variety of course directions. Some of them I acquired from others, but they aren't popular with my clients. The calendar helps me highlight exactly which ones are worth promoting! Recently, I've even managed to sell the least sought-after ones. At the beginning of the year, I identified specific promotions by month and quarter, and people like it. They have become much more responsive. I send out emails with course offers, and even "inactive" clients easily get activated at this stage. It's especially nice when a customer comes back for more and recommends the courses on social media! The calendar delivers results without any additional investment on my part!
