Just a quick post about emails that are confusing me. I really cannot see why they are sending them. There is no obvious tracking or malware involved. I can understand if there was a hidden tracking beacon to tell the spammers/scammers that the email address was active, but I can’t see one anywhere. I suppose they could be relying on a bounce back if undelivered but most properly set up email servers don’t bounce spam although they should bounce non existent email addresses unless they are part of a dictionary attack. It just seems a very inefficient way to see if an email address is live and able to receive mail by relying on bounces.
Over the last few weeks I must have received 50 or 60 similar emails to several email addresses. At first glance they look like a read receipt, but with garbled content when in the junk/spam box in outlook ( viewed in plain txt). They only display as html in inbox.
Does anyone know why these are being sent. Please reply in the comments section below or in This Twitter thread.
