ChimpMailer
Currently a thin wrapper around the MailChimp API.
Will eventually be expanded to integrate into Rails in many awesome ways.
Installation
gem install chimp_mailer
Example
In your environment.rb:
MailChimp.settings = { :api_key => 'YOUR API KEY HERE' }
Then you can call any MailChimp API method like so:
MailChimp.campaign_schedule(:cid => 'afd3245', :schedule_time => '2010-06-21 12:30:00')
