Also, it looks like we send ~4 million emails per month. This would put us in Mailgun's first-class tier which is a graduated tier. At this volume, it would cost nearly $1,000/month to have them send all of our emails. To use the "Campaign" feature, the cost goes up by 50%. We might be able to talk to them about a discount given that we're an open source project, etc.

I don't know that spending that much money on email is worth it when we already have a somewhat functional solution. The thing with the news post emails can be addressed by just having a send_email_batch worker so that they run separately from the normal email workers. That would be pretty easy to build.

Anyway, there ya go. Some data!
