I want to start sending out monthly newsletters and announcements in the next month or so to keep my customers updated about goings on. I keep seeing constant contact and wanted to see if anyone used that or if something else worked?
You can do this in yardbook also. If you use a generic email , like outlook, make sure you blind copy everyone, so they all don't get everyone else's email addresses.
