Imported users not receiving verification emails due to massive Sidekiq backlog

There has to be a logical explanation as to why user validation emails are not reaching mandrill

Yes, there is.

It’s exactly like @riking said:

@riking

What’s likely happening is that the email jobs are stuck in the queue behind all of the post processing jobs from the import.

You can try to temporarily setting UNICORN_SIDEKIQS to a higher number (e.g. 5) in your app.yml in order to process the queue a lot faster. But, this will use a lot more memory. So, make sure your machine has enough.

BTW: I was wondering if it’s possible to enqueue high priority tasks like sending validation emails before all other tasks? Does Sidekiq support this? Everyone expects emails to get sent immediately, but nobody cares about how long it takes to postprocess posts.
