How can I send mail with rails without a template?

Question

In my Rails 3 project, I want to send some simple notification emails. I don\'t need to make a template for them or do any logic. I just want to fire them off from various place

Answer 1

Rails 5 users may find the accepted answer (using format.text {...}) doesn't work; at least I was getting an exception because Rails was looking for a view.

Turns out there's a section in the Rails Guide called Sending Emails without Template Renderingand all one needs to do is supply :content_type and :body options to mail(). E.g.:

class UserMailer < ApplicationMailer
  def welcome_email
    mail(to: params[:user].email,
         body: params[:email_body],
         content_type: "text/html",
         subject: "Already rendered!")
  end
end
