Advice from a MailChimp expert

I need 1-2 hours advice on how to get the most out of my MailChimp campaigns. I have a list of c1700 contacts and have some segmentation too - but want to know how to add new contacts to segments and also to get good tips and tricks from a MailChimp expert. So far we have used e-marketing a few times a year - we're now setting up newsletters and sales campaigns and need to get our lists in order.

I have a free MailChimp account and would like to discuss limitations to this and what difference a paid subscription would make.

Please only respond if you REALLY understand MailChimp inside out and are able to explain to a busy business owner in straightforward terms.
