Just engage a marketing service to send them out for you. Or, better yet, set up a web page (Weebly
makes it both easy and free) for your 2,000 members to regularly visit.
Or, how about a Facebook page?
As for me, I get about 400-500 "junk" emails a day,
and, obviously, not a single one of them gets read, or ever will. (GMail filters out over 97% of all the traffic that it receives.) Therefore, I don't consider email to be a viable way for people to remain in contact anymore.
