I would suggest that you take a look at other email marketing applications, like Emma. I worked with it at a previous employer. It's not perfect, but there's SO much more you can do in Emma. Constant Contact is so limited. You can only set-up your email one basic way. Take a look at what they offer and maybe try expanding your offerings and giving clients more ownership of their emails. We send so many emails to our clients and tired of having to make emails look the same way. It's boring. Step outside the box Constant Contact.
