Book buyback campaigns are held to help students make some money back off expensive textbooks while also providing new students with a lower-cost used version of these books. It is important that students know when the campaigns occur. Create an SMS keyword that students can text to opt-in to get reminders about the buyback program. You can also create an online form for students to fill out to receive the reminders via email instead. Now you can set up a drip campaign so students will receive email and SMS reminders before and during the book buyback event.
