A guest has come in the last four weeks in a row; you start finding out more about them, you use this knowledge to reference the next time they come in; the guest is blown away that you remember. You offer them suggestions based on the things they like, they feel a connection. You have built a relationship with the guest.
Why not do the same with your digital media. Learn about your guest, ask them questions, then send them follow-up messages and offer them suggestions based on what you know about them.
Build a relationship!
