Why does it get timed out when using nginx?

I'm running rails on nginx. Then I have the function to deliver emails to all regiestered users at once.
I did ran this but it got timed out error. How can I fix this? How can I modify my configuration?

controller (There are over 10000 users so it means this mailer procedure repeats for 10000 times)

users.each do |user|
    if user.nomail.blank?
        CallMailer.call_email_to(user.email, subject, body).deliver
        sent_to_count = sent_to_count + 1
    end
end

Then it gets this timed out error.

The connection has timed out
The server www.foofooexample.com is taking too long to respond.

Here's my nginx's conf

etc/nginx/conf.d/foo.conf

server {
    listen 80;
    server_name foofooexample.com;
    root /var/www/html/foo/public;
    client_max_body_size 5M;

    keepalive_timeout  1200;
    proxy_connect_timeout 1200;
    proxy_read_timeout    1200;
    proxy_send_timeout    1200;

As one of the comments mentioned, you want to offload this to a background worker using something such as sidekiq, which comes with an ActionMailer extension for sending email in the background.

After installing, instead of

CallMailer.call_email_to(user.email, subject, body).deliver

You would use:

CallMailer.delay.call_email_to(user.email, subject, body)

Also, I'd advise you use find_each instead of each. This is because each will load all of your User objects into memory, whereas find_each will load them in batches. See the linked documentation for example usage.
