newsletter

This plugin let you to collect subscribers on your blog with a double opt-in subscription process. Double opt-in means the user has to confirm a subscription following some simple instruction sent to him by email. Each step of subscription and unsubscription processes is fully configurable (almost fully configurable). The plugin has a simple visual composer to create your newsletter and send it to subscribers.

The subscriber management is still really stupid, but it is enough to search emails and delete them.
