Sending multiple emails using Rails

Question

Any problems sending a lot of emails with rails like this:

@members = Members.all
@members.each do |m|
 MemberMailer.message(@message, m).deliver
end

Answer 1

The major problem would be if you are a user and somehow when you signup or try to send those emails through some action, the server could return a timeout response, if you have a lot of users. What I recommend you to do is, put all mailers call inside a worker like sidekiq or sucker_punch. it will help a lot with rake tasks in and other piece of code in background jobs.
