ActionMailer:Base Validation


Hi all,

I’ve used below link to send mass emails to people.I am able to send
using the same code without any issues.

Now,Is that i need to validate Subject,Recipient,Message text boxes.Can
you please suggest me how this can be achieved.As i am very new to rails
and i beleive ActionRecord cannot be used here as we are using
ActionMailer for sending mass emails.

Appreciate your quick response with some example to do or any steps.
