title: What is the best way to schedule a sending-email task with Ruby on Rails?
body: <p>I would like to schedule a daily task : every day at 7 AM, I want an email to be sent (without human intervention).</p>
  
  <p>I'm working on the RoR framework and I'm wondering what is the best way to do that?</p>
  
  <p>I've heard about BackgrounDRB, OpenWFEru scheduler or things based on Cron, but I'm a newbie and don't understand which one is made for my need.</p>
