The easy way I would do it is have a scheduler that would sent reminders.

There's several schedulers available. Here's one: http://github.com/jmettraux/rufus-scheduler

For the mailer, you can use the provided mailer in Rails; ActionMailer::Base (http://api.rubyonrails.org/classes/ActionMailer/Base.html)
