How to Use MailChimp to stay in touch with Existing Customers
Send customers your latest content. Based on what form they completed on your website, you can even send content only to contacts that have previously shown interest in that topic.
Educate them on features. For example, you could create a three-part automated email series on how to use a specific feature of your tool.
Let them know about upcoming events and release. Consider creating a list or MailChimp group for product releases so your contacts can elect whether or not they want to receive emails about upcoming releases.
Send them some thing for free . Instead of only creating eBooks to attract new signups, how about sending those same eBooks to your already subscribed contacts?
