To me, time spent making a better email distribution might be better spent developing a social media presence. Making it easier to blast emails makes your life easier, it does not necessarily broaden communication or reach more members. Some people are sending your emails to spam but might feel guilty about hitting the unsubscribe.

Social media gives people an ability to connect with your organization rather than just receive notifications. It lets an organization meet people where they are...nobody wants to be "on email".
