simple_mailer

simple_mailer is a very simple email library for ruby, with testing support. It just uses ruby’s standard net/smtp library to send out the emails. Configuration is limited to setting the server that the email is sent to (defaults to localhost). Testing support is limited to appending the emails that would have been sent to an array.

simple_mailer can be installed with:

    sudo gem install simple_mailer

Source is available at github: github.com/jeremyevans/simple_mailer

RDoc is available at: code.jeremyevans.net/doc/simple_mailer/

Usage

There is no required configuration, you can use simple_mailer immediately:

  require 'simple_mailer'
  SimpleMailer.send_email('from@from.com', 'to@to.com', 'Subject',
    'Body', 'HeaderKey'=>'HeaderValue')

Or, you can include the SimpleMailer module in other classes:

  class Mailer
    include SimpleMailer

    def initialize(subject, body)
      @subject = subject
      @body = body
      self.smtp_server = 'smtp.example.com'
    end

    def email(from, to)
      send_email(from, to, @subject, @body)
    end
  end
  Mailer.new('Subject', 'Body').email('from@from.com', 'to@to.com')

Testing

Testing support is probably the main reason to use simple_mailer over using net/smtp directly. After you enter test mode, emails you send are available via the emails_sent option:

  SimpleMailer.test_mode!
  SimpleMailer.emails_sent # []
  SimpleMailer.send_email('from@from.com', 'to@to.com', 'S', 'B')
  SimpleMailer.emails_sent # [[message, 'from@from.com', 'to@to.com']]
