How To Change The Subject Of A Devise Email

Posted by Weston Ganger on August 02, 2016

Sometimes you may want to change the subject of a devise email. This also works with devise_invitable. Its pretty simple.

First tell devise we want to use a custom controller:


# config/initializers/devise.rb
config.mailer = "CustomDeviseMailer"

Then create the custom devise mailer. In this example I am overriding the devise_invitable invitation_instructions email:


# app/mailers/custom_devise_mailer.rb:
class CustomDeviseMailer < Devise::Mailer
  protected

  def subject_for(key)
    if key.to_s == 'invitation_instructions'  
      "You have been invited to Super Awesome App"
    else
      return super
    end 
  end
end
