There was an issue with the mail server this week-end and it is not completely fixed.
Generally the mail does not take that long to reach you, this is an unfortunate circumstance.
All, moreover, when supposed to receive a mail, please check your Spam/Junk folder by connecting DIRECTLY to your email provider web interface.
Mail clients (outlook/thunderbird) tend to not download the mails in there as consistently.
Connect to the web interface and manually check your emails, and sometime you have good surprises in there.
