Hi,

to send an email with ar\_mailer I need to generate it and save it to  
the db, right?

Currently the code looks very simple:  
Newsletter.recepients.each do |recepient|  
NewsletterMailer.deliver\_dedicated(request, recepient, newsletter)  
end

But for i.e. 30000 receivers it’s going to take a long while anyway.  
Should I create them somehow in the background using BackgrounDRb or  
something similar? If I should, then I could get rid of the ar\_mailer  
and just send all emails in the background… The only advantage of  
ar\_mailer in this case would be the functionality to send emails in  
batches.

Any thoughts?

The use of backgroundrb is to divorse the long running the tasks from  
controllers.

if you use ar\_mailer you rails app will be overloaded. So its better to  
go with backgroundrb.
