After studying several email service providers, narrowed my choices to four including Constant Contact. I signed up for free trials for all four services so I could test them as far as features I want, which include adding a sign up form to my site. I can't even test that out unless I go ahead and pay for a plan. I also see that I don't have autoresponders unless I pay $45 a month, which is too pricey for me. Guess I won't be using Constant Contact.
