Answer 1

The deliver method is the one that sends the email, so you can do this:

def send_emails
  # You can set here the email with attachments and all stuff
  mail = MyMailer.send_message("demo@example.com")
  body = mail.html_part.body

  User.all.each do |u|
    mail.to = u.email
    mail.html_part.body = body.gsub(/user_id/, u.id)
    mail.deliver
  end
end

Of course it's better if you set this method for background processing.
