I have been designated by high school classmates to send out mass emails for our class reunions. Mind you, we graduated decades ago. I initially set up YAMM with my personal email but quickly realized this was not the right way to go. I needed to send the mass reunion emails out from out the reunion email account. I put in a request to YAMM to please transfer my YAMM subscription over to the class reunion account. YAMM responded quickly and fixed it for me.
