Every month I offer different specials. Some months it will be a discount on a certain kind of shoot, for example, "30% off Newborn Photos", and some months there will actually be free giveaways! Though I do often post my monthly specials on social media, some of them are first come first served, so the best way to keep up is by signing up for my mailing list. To show my appreciation, I also throw in exclusive offers from time to time to the good people on my mailing list. I never bombard my clients with emails; 1-2 messages a month at the most.
