We have a number of problem reports, from various blog owners and readers, about email from Blogger, posted daily in Blogger Help Forum: Get Help with an Issue . Some email, from different Blogger features and services, simply is not being delivered. The normal advice given is for the person reporting the problem to look in the "Bulk" / "Spam" folders, in the email client. Not all non delivered email is dropped into "Bulk" / "Spam". Some email is simply "bounced" - ie, returned to the sender. Since most Blogger email is sent from a "no-reply" email address (ie, "no-reply@blogger.com"), bounced email vanishes - and nothing is done to analyse its non delivery.
