Prior to Chamaileon, it made sense that I was creating blasts for our company since I’m a graphic designer. But that quickly became a heavy workload for me alone. Since Chamaileon allows for a multi-user/team environment, I was able to train other employees in this user-friendly space which ultimately helped lighten my heavy workload.
