Hi,
Your idea is perfectly matched with an app we're developing, you might be interested in: http://beeketing.com
We're building a marketing automation tool to help you:
- track & analyze customers' behaviors to learn their interest
- automatically send follow-up emails based on their behaviors
Our app will be released soon, starting with Happy Email.
I hope this is what you're looking for. If you have any feature suggestion, please let me know. We'll try our best to make it happen.
