This is an uncertain time. Using printed cards helps engage with your customers either current or past to keep everyone connected like the community you always have been. Even if apart. Staying home and staying safe doesn't mean staying unconnected.
Just purchase a few of these We Miss You cards, fill them out, write a personalized note to the student, add their address, put a stamp on them and drop them in the mail.
People get really motivated when they know you care about them and what better way to communicate that than with a handwritten message. It really motivates students to get back to class. Try them out now and engage with students who have been missing for a bit.
