Skipping the part about creating a task in crontab, here is what you can do:

1. Create a rake task, in lib/tasks, which sends that email and invoke the rake task from your cron job. I have done this and this works, pretty well for me.

2. Load the Rails environment explicitly in your ruby script. I do this in some daemons. You can do something like this :

   require File.dirname(__FILE__) + "/../config/application"
   Rails.application.require_environment!
   

3. Use the rails runner. rails runner -h will give you the necessary information
