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.

This plugin is very useful and also allows tracking of whether recipients have opened the email. However, one area for improvement could be that test emails sent to oneself also count toward the quota. Perhaps a feature could be developed to preview the email content without using up the sending limit. Also, if the free quota can slightly rase to 30, it would be really helpful.
