WPMQ extends the default WordPress wp_mail() function to allow emails to be added to a database table for sending later.
A menu is added at Tools->Mail Queue that allows Administrators of WordPress sites to set limits on the number of email sent and the frequency with which the mail queue is processed. This menu also displays the number of emails currently residing in the queue.
This is an ideal plugin for use with Subscribe2 if you are running into limits imposed by your hosting provider and you can't or don't want to move to a more feature rich hosting package.
