MailChimp campaign is a complementary module for the MailChimp module, which allows you to create campaigns from within your Drupal site.
It leverages standard Drupal nodes for preparing your campaign content and does all the work of sending it to MailChimp using their API. As it uses nodes you can format your content any way you'd like, including using nodereference fields to pull in and display other nodes, or maybe embed Views in your node to show lists of content. Basically anything you can do with CCK based nodes you can send to MailChimp as a campaign.
It integrates with MailChimp using their 1.3 API. In its current incarnation it handles almost all the parameters in campaignCreate (see http://apidocs.mailchimp.com/rtfm/campaigncreate.func.php) but not all have been fully tested. Most importantly it handles segmentation so you can send your campaigns out to segments of your list, e.g. interest groups.
The Convio Integration API is basically a connector module through which you would send requests to the Convio API to gather specific pieces of information from your site.
The Keyword Research module provides intelligence to help you explore, analyze and select better keyword phrases for your content directly from your website. It also enables you to quickly and easily organize your targeted keywords and tag pages using a variety of popular methods.
The module provides reports on a keyword phrase's popularity and the popularity of suggested related phrases using various data sources such as; Wordtracker, Scribe SEO, WordStream and Google Adwords. It also provides convenient links to a variety of third party tools, such as Google Trends, Google traffic estimator and GoRank’s related keyword tool for additional insight.
It wraps any keywords generated by supporting modules and all keyword in research reports with a pop-up actions menu that enables one click popularity reports and adding & removing keywords in taxonomies, More Like This, and meta keywords.
