I just went to my hotmail account to check the full URL, and clicked on it.
The page opened as normal on the WordPress site.
I don’t have the URL of the second lost page after having deleted the email notification. I received the notification yesterday, but the blogging site I follow shows no record of any posts for that date.
Anyway, things seem to be working OK now.
Thank you for replying in this thread though and sorry for wasting your time about this.
