Rails: Best way to schedule emails

Question

Scenario: "I have 500 different types of posts (So emails are being sent various scheduled days exactly at 7 o'clock in the morning). A user signs up to receive 1 or more of those types of posts every day via email (keep in mind, this could mean 5,000+ emails per day)."

Looking around SO, I keep seeing the "Whenever" gem come up as a solution but some are saying that it could cause spikes in the server. I also read some posts on delayed_job but some say that it freezes which I do not want to happen. I googled some more & still could not find anything close to being specific to my question.

What would be the best way to handle this, given my scenario & why?

Thank you in advance.

Answer 1

Use:

http://rubygems.org/gems/resque

in conjunction with:

https://rubygems.org/gems/resque_mailer

The best part is that you won't have to change the code, you just can send them like you did with ActionMailer!
