The title should have been "How we send 22000 emails every hour for $9/month"
16 million emails for $9 is actually pretty good.

It's nice to see that a small-to-medium-scale mail server is still a possibility in this time of Gmail/Hotmail bans, IP blacklists, and the like.
On that note, I wonder what happens when a scam caller dumps a SIP number and a legitimate business unwittingly picks it up when they open. Now a hundred thousand people have blocked it in the phone and it's blacklisted on several apps.
Is that a spam system?
> No, [...] marketing.
Excuse me while I lol.
(It might be completely wanted marketing, just amused me; almost all spam is marketing for something.)
[EDIT] I mean 1% of marketing emails where there's any relationship between the sender and the recipient whatsoever, of course. All others are spam, clearly.
