What can I say about MailChimp. How about that it is the email service that powers the Plannerwire | i3 Events newsletter. MailChimp is awesome. Amazing even! And they start at the whopping price of FREE! Cost effective, amazing features, and super easy to use, MailChimp should be on the short list of anyone that is planning a conference or event and needs to stay in contact with their audience and fans. Love this product.
