Cannot send multiple emails in a loop

This is my first Rails project, and I may be missing something
obvious, but... I need to send emails to a group of people, but the
content is individualised, so I cannot bcc them, so I put it into a
loop. It sends the first email OK then fails with an "uninitialized
constant Admin::PrivateNewslettersController::NewsletterMailer" error.

Fore testing I have reduced it to 3 addresses in test_arry, and taken
out the encryption processing.
In the controller I have:
test_arry = ['email1@mac.com', 'email2@mac.com', 'email3@me.com']
     test_arry.each do |an_email|
        email = an_email
        name = 'john'
        encrypted = ['abc']

        NewsletterMailer.newsletter_email(email, name, encrypted)
      end

In the Mailer I have:
class Admin::NewsletterMailer < ActionMailer::Base
  default :from => "administrator@xxxxxxxx"

  def newsletter_email(email, name, encrypted)
    @name = name
    @url = "http://www.xxxxxxx/nl/download/"+encrypted.to_s
    mail(:to => email, :subject => "Dark Peak Newsletter")
  end

end

    NewsletterMailer\.newsletter\_email\(email, name, encrypted\)

That should probably be Admin::NewsletterMailer,if your controller
isn't in the Admin module I suspect you're getting lucky the first
time round due to a quirk in the rails magic auto require stuff.

Many thanls, using Admin::NewsletterMailer does seem to have fixed it.
