The Newsletter plugin has an extensive set of options for who want to configure it even to the finest detail but it usually works greatly out of the box. Newsletter is composed by different modules which actually correspond to the main activities a blog owner needs to deal with on a mail marketing system:
- the subscription, confirmation and cancellation process (and the related forms)
- the subscribers management
- the creation and delivery of newsletters
- the analysis of the mail campaigns
To read only the most significant parts of this documentation you can concentrate the attention on the delivery engine and the related speed questions, the subscription forms documentation where you can find the HTML rules for the fields, the newsletters’ themes customization and their file system location to avoid to loose them on plugin update.
Questions not answered on documentation can be asked in the forum.
