For one, it's pretty challenging to send out 43M similarly-looking emails within 24h without tripping a whole bunch of anti-spam filters - even when you're using tailored services (that distribute over IPs with good rep, etc) like Amazon SES.

No its not. they are called transactional emails and dont get blocked. Usually, you have a dedicated IP for that which guarantees fast delivery.

  This is silly – the entire process of "Oh, we got hacked. What did they access? Who's been compromised? Better write an email. Better find a channel to send that email, and wait for it to be sent" could very, very obviously take a couple of days. You are unfairly trivialising that.

    My point was transactional emails does not hit any spam filters. And since email services tracks how many of emails were opened, i am pretty sure 'we have been hacked' will be opened quite often and will never be in spam folder.

      From the point of view of a spam filter, there isn't really any difference between a "transactional" (what a horrible name, but not your fault that the industry has adopted it) email and any other email. "Transactional" emails simply have some distinctive elements, such as the first and last name of the customer, which make them less likely to be filtered out.

        First & last name in email alone doesn't guarantee to hit inbox. Huge free email services use social 'signals' as open rates, 'this is spam', 'this is not spam' as well as IP reputation i mentioned earlier to determinate if email hit inbox. So, there is obviously a difference in those metrics between simple notification 'your account have been hacked. change password' and 'hey, we haven't seen you for ages'. As email system notice high user involvement it will never ever block such emails. Actually, i think it will increase IP reputation.

      "transactional emails" is a term marketers use, but in reality the email systems do not know the difference. And yes we did get stopped by various ISPs, and yes we did have to get some on the phone.

  As I understand, transactional email is often triggered by a user itself (new account creation, forgot password, etc). By definition, those are sent spread out over time. This is - at least from a spam filter's perspective - a huge email broadcast, more akin to a news letter mailing or a spam run. And semantics aside, a lot of those 43M users will consider the email to be unsolicited (didn't remember they signed up, don't care about computer security, etc). They will happily report such an email as spam, adding to the training set.
