I needed a way to send an email in the future, so I came up with WP Delayed Email. Activate the plugin, and you can call wp_delayed_mail() just like you would wp_mail(), except that you pass a timestamp argument for the time you want the email to be sent.

Excellent plugin! And very user friendly, we had it up and running in no time. It will definitely save lots of time and keep things in order.
