From personal experience, if you're not jumping straight from no emails to a million an hour, your mail setup is good (SPF/DKIM/etc), you're not reusing a IP address that was sending spam last week (so be wary sending from cloud servers), and you aren't actually sending spam, then you can send from your own infrastructure just fine.

This is true, with the exception of AT&T. The Deathstar rejects all mail from my server, despite (a) no spam ever having been emitted from my domain in almost 20 years, (b) the IP having been stable for coming on eight years, and (c) I don't send bulk mail. Best I can tell, their blacklist-removal process is auto-deny with no humans in the loop. I gave up and decided screw them, I don't need to talk to anyone with an…

Great discussion here, not necessarily about the OP's link, but still learned a lot. Would love to contribute my 2 cents... Our app[1] sends/receives several million emails per month. Not an exaggeration, it's actually seven figures. Meaning it's more than 100k a day. Meaning it's 5-6 emails every friggin second. On average. It, of course, peaks during US daytime, up to 30 per second. We tried a looooh-ot of solution…

Hey, So firstly, I don't work for AWS or Amazon, or any Cloud provider. Just wanted to make sure that was clear. After reading your very interesting comment I thought I'd do some maths on the costs SES should be charging you. Essentially at $0.10 per 1,000 messages, and sending "several million" or "seven figures" worth of messages per month, so a possible total of 9,999,999, you should be paying almost exactly $1,00…

How about redundancy when your $4 a month VM goes down? If you're sending/receiving that much e-mail, I assume uptime is critically important.

yes, but as someone who's worked on the sending of emails side of this i can assure you that the techniques for fighting spam are TOO effective. There are many legit emails that go into black holes before any standard idea of spam filtering comes into play. I wrote an embeddable smtp server so that you could have an app that sent email without ever asking your users to put in their SMTP server info... it was USELESS…

I hear this all the time, but the culprit is always someone sending spam, who does not consider it spam. Usually stuff like missing unsubscribes, spammy language, sending bulk to bought email lists, etc.
