Mailchimp

Description

I need someone to help me do the following in MailChimp:
- Create 3 audience types for 3 different mailing list topics (add some pre-existing contacts into the relevant groups)- Create 3 subscribe buttons for the website so people can sign up for 1, 2 or all 3 mailing lists- Create a simple email campaign so we can ask our contacts for their preferences for receiving comms relating to the 3 mailing lists
