Hi again, Thank you to the few people that responded to my first post. The information I received about Mailchimp.com and Constant Contact has been very helpful. At this point I'll ask if there is anyone else willing to take a few moments to share? What is the name of the program or software you use? - is it efficient? - is it user-friendly? - Are you happy with it? What were the up-front costs for the program/software? - were there any long term costs to consider? Has your library seen an increase in program attendance with the use of the opt-in email list? - or other indications that the email list is working? For those of you that asked me to share the responses I will be sending the information out shortly. Thanks, Sarah Scherdt Adult Reference Librarian White Lake Library
