Sending email to multiple recipients

Hello,
   I have to send mail to multiple recipients. My table is named people
and has
first_name,last_name, email1 , email2, email3 for each person. i have
put people in various mailinglist .For example first mailinglist where
first_name is john or say the second mailing list contains people of
british origin.etc

the relation between mailinglist and people is many to many.
params[:ml] gives me the id of the mailing list to which mail is to be
sent.
In the controller i have

def sendmail
  @mailinglists=Mailinglist.find_all_by_id(params[:ml])
  @mailinglists.each do |ml|
  @people
Person.find(:all,:include=>:mailinglists,:conditions=>[''mailinglist_id=?'',"#{params[:ml]}"])
UserMailer.deliver_send_mail(@people)
end
end

In the mailer model which i have named as user_mailer i have

class UserMailer < ActionMailer::Base
  def send_mail(people)
#----------------------------------------
    recipients people.email1
# this generates error undefined method email1
#---------------------------------------------------

    from
"christoph.von.luttitz-22st+ISarquReoB3siuDrpaahg+LTQ92@public.gmane.org"
    subject "Thank you This is a test"
    body      "This is a test"
  end
end



The recipients people.email1 generates an error undefined method email1
.
If i use the same code for person instead of people i.e if i send mail
to only one person and pass person as a parameter as

def send_mail(person)
recipients person.email1
...
...
then it works fine but i am able to send an email to only one person.
Please tell me what am i doing wrong and how do i proceed.

Thank you.
Regards,
Ank

Perhaps this works.

Re: Sending email to multiple recipients

If you have thousands of email addresses then you must use ar_mailer. It is
asynchronous and will not impact the performance of your Rails app. Check
out the Rails Way book for a good discussion on this issue.

Just a matter of opinion, but you might consider moving your email  
addresses to another table so you don''t have to limit your users to  
three.  I like to use a construct called "contact number" which can  
be a phone number (landline or cell), fax, email, page, url, im,  
whatever.  Then you can have as many as you want and iterate through  
them as a collection.  But that''s just a matter of style and need.

recipients is an array, so you need to build all of the addresses as  
an array.  The collection people does not have a method called  
"email1", that is an attribute of each person object.  So
you''d need
to do something like this

people.each do |person|
	# this is more personal than just the email address, but that would  
work too
	recipients << "#{person.first_name} #{person.last_name} <# 
{person.email1}>"
end

I don''t know about the performance of ActionMailer with thousands of  
recipients, so Bala''s advice might be your best bet.  And I would not  
use Jochen''s advice (absolutely no offense intended, Jochen!) and put  
each delivery in a loop.  In that case, you''d be sending a single  
message for every recipient instead of sending one message to your  
outbound server and letting it handle the multiple recipients.

Oh, one other thing:  use bcc instead of recipients.  It''s generally  
considered bad etiquette to send out a mass email and put everyone''s  
address in the to line.

Peace,
Phillip

A little ruby should fix this.

Instead of

  recipients people.email1

try

 recipients people.map {|person| person.email1}

different address seperated by comma.

Thank you.

Thanks a ton Philip...One final question regarding mailing. The use 
wants to create templates and that will be in html format....The user 
will not know anything about HTML code so he will copy and paste the 
text from WORD to the textbox provided in the email interface of rails. 
Any suggestions how do I convert that code to html while pasting or it 
would be even better if it is possible to create a text box gmail style 
i.e. which has colors and fontsize options.... Sorry for so many 
questions. I am somewhat new to ruby and rails...and have a project to 
complete in rails.

Sorry, I can''t be of much help here.  I have not yet had a need such  
as this and therefore have no experience working it out.  I''m sure  
that someone else on here will have some great ideas, though.
