List Management

Mailster enables users to create and manage list of subscribers. Click the “Lists” button on the sidebar of WordPress. Then click the “Add New” button.

The plugin displays the lists you have created and the number users who have subscribed to them on one interface. It displays the date the list was last updated as well as the date a new subscriber was added.

To help you differentiate/identify subscribers, each subscriber is assigned one of the following statuses in the Mailster application:

  • Unsubscribed, Subscribed.
  • Pending, Error, Hard bounced.

While setting up the newsletter, the plugin will prompt you to choose the list of subscribers. Mailster gives users a rating. Based on user activity, the rating is calculated. The user’s rating will rise if he/she opens your newsletter. Users who have unsubscribed to your newsletter will see their ratings decrease. This feature allows you to determine which users are most interested in your content. To increase your website’s/blog’s revenue, you can send top-rated users coupons and deals.
