Mail not sent: sendgrid on heroku using Ruby on Rails

Question

I'm attempting to send mail from ruby on rails app on heroku via sendgrid. This is a standalone app only trying to send an test e-mail. I get no errors but the mail is not sent. Your help is appreciated.

== config/environment.rb === 
    ActionMailer::Base.smtp_settings = { 
    :user_name => ENV['SENDGRID_USERNAME'], 
    :password => ENV['SENDGRID_PASSWORD'], 
    :domain => ENV['SENDGRID_DOMAIN'], 
    :address => "smtp.sendgrid.net", 
    :port => 587, 
    :authentication => :plain, 
} 
===

==== config/environments/production.rb === 
    config.action_mailer.delivery_method = :smtp 
    config.action_mailer.raise_delivery_errors = true 
=====

== app/models/notifier.rb == 
    class Notifier < ActionMailer::Base

    include SendGrid 

    default from: "[email protected]" 
    #sendgrid_category :use_subject_lines 
    #sengrid_enable :ganalytics, :opentrack

    def test_notification 
      mail(:to => "[email protected]", :subject => "mail from heroku") 
      puts("Sent mail from notifier") 
   end 

   end 
========

I tried running the test_notification method from heroku console

>> Notifier.test_notification

(This prints out some log info..)

#<Mail:Message:279922420, Multipart: false, Headers: <from.., To, Subject, etc).

But send_grid doesn't report any mail sent out from my account. Not do I receive the e-mail.

I have also tried to send mail by an other means by calling test_notification from /home/index/controller which will be sent when visiting the home page of the app.

=== 
class HomeController < ApplicationController 
def index 
Notifier.test_notification() 
end

end

===

Stats don't report the mail as sent either. Any help is greatly appreciated.

Thanks! DS

I'm having the same issue. I think the integration is just broken. I've written support. We'll see how that goes. — devinfoley

try

Notifier.test_notification.deliver

you need to call the deliver method on your method to actually send the message.

Make sure you have a SendGrid add-on to your Heroku.To the code

user_name => ENV['SENDGRID_USERNAME'], 
:password => ENV['SENDGRID_PASSWORD'], 
:domain => ENV['SENDGRID_DOMAIN'],

the details should be your sendgrid username,password and domain

is domain necessary? What does that do?
