It's impossible to say -without seeing server logs - why an email didn't arrive; it might not have been sent, it might have got lost en-route, it might have arrived but been deleted by the receiving system (eg at the SMTP gateway), or - lastly - it might have arrived but been misfiled in your folder hierarchy.
Having said that, it's clear to me that some sending email systems do not do retry at all. I've had (paper) letters from banks telling me that my email address is invalid and asking me to define it ... even when they've previously sent me email.
I think either their sending system does no retry and one failure (eg no route to the receiving system, or the receiving system is down for maintenance, or suffering a DDOS attack or...) and they give up. Decent systems retry - at intervals for up to a week.
Alternatively, although you'd think their computer systems have stored my email address and automatically use it when emailing me, maybe things are primitive and some clerk c&p my address from one place to another (which should be fine) or retypes it by eye (which might not be).
I have found it impossible to get normal cistomer service staff to engage on this matter, so these days - when I can be bothered - I raise a formal complaint with the bank(s) in question, asking for their evidence (ie SMTP logs) that they sent the email and asking for the log detail to show that a receiving system actually accepted it, or rejected it.
