Use this plugin to maintain a simple mass mailing list and send simple html e-mails to the people in the list.
With this plugin you can maintain a simple mailing list and send html e-mails to people in this list straight from your own server.
People can sign up to your list and a confirmation e-mail is supported for that.
The plugin supports 'batches' so if your hosting provider limits the number of e-mails you can send in a certain amount of time you can split your sending up.
Users can subscribe from the front-end. Just add the string [ifsmailersignupbox] in any post or a div with id "frontendaddemail" in any post or theme area: <div id="frontendaddemail"></div> to add the subscription form.
A confirmation e-mail is being sent to the person signing up to verify the e-mail address.
Users can unsubscribe with the the unsubscribe feature.
