In that scenario, how much does it really matter? It’s free to send email at one time of week rather than another, so your only cost is the opportunity cost of picking a bad time to email people, which doesn’t seem likely to be too big.
Our email send by the hour would get far lumpier, so we would have to add more servers in order to handle a much higher peak emails sent per minute. And it takes development effort to configure emails to send at an intelligent time based on the user’s timezone.
