12 Tips of Christmas - 8 Send Emails with Sidekiq

To help ensure users get a fast experience within your application, one tool you can utilise is Sidekiq to process any sending of email you might be doing asynchronously. 

To get started, just add the following line to your Gemfile

gem 'sidekiq'

You'll also need redis, so if you haven't got that installed run the following:

$ brew update

$ brew install redis

$ redis-server /usr/local/etc/redis.conf

To run Sidekiq:

$ bundle exec sidekiq

Sidekiq supports sending emails with ActionMailer off the bat, all you need to do is call delay before your mailer method instead of using deliver eg:

UserMailer.delay.reminder(@user)

We can also call delay_until to delay the email send until a specified time.

All too easy
