We had sidekiq jobs setup to send out emails. We made a few changes to the template one day and then it started.
Some outgoing email had the new email template and some were still using the old template. This baffled everyone on the team, QAs were frustrated too since they could not reproduce it consistently in the QA env. This was supposed to be rolled out the next day, hence a sense of urgency too.

BUG

We had recently setup a new sidekiq jobs server and did not decommission the old one (we planned to use it for another env). The new code was deployed to the new servers. Whenever the old server would pick the job it would send out an email with the old template causing the confusion.
