Christopher Sexton developed a Simple Capistrano email notifier for rails. You can find details at
Here is Rails 3 port of the notifier.
The notifier sends an email after application deployment has been completed.
How to use it?

2. Update the file with your google credentials and from email address.
3. Add the following content to config/deploy.rb.
require 'config/deploy/cap_notify.rb'
# add email addresses for people who should receive deployment notifications
after :deploy, 'deploy:send_notification'
# Create task to send a notification
namespace :deploy do
desc "Send email notification"
task :send_notification do
4. Update deploy.rb with destination email addresses for the notifications.
5. To test run this command:
cap deploy:send_notification
require "action_mailer"
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:enable_starttls_auto => true,
:tls => true,
:address => "",
:port => 587,
:domain => "",
:authentication => "plain",
:user_name => "YOUR USER NAME",
:password => "YOUR PASSWORD"
class Notifier < ActionMailer::Base
default :from => "YOUR FROM EMAIL"
def deploy_notification(cap_vars)
now =
msg = "Performed a deploy operation on #{now.strftime("%m/%d/%Y")} at #{now.strftime("%I:%M %p")} to #{}"
mail(:to => cap_vars.notify_emails,
:subject => "Deployed #{cap_vars.application} to #{cap_vars.stage}") do |format|
format.text { render :text => msg}
format.html { render :text => "<p>" + msg + "<\p>"}
