I’m running into the same issue. For example, on this post two of the Related Posts featured are “The Girl with all the Gifts” and “I Am Not a Serial Killer”, both of which have a featured image and an in-post image yet their thumbnails are the default blank image. I’d love a solution to this bug. Thanks!
Thank you! I’ll review # 3 (#1 and #2, done) and let you know what happens. I sure hope the e-mails aren’t getting auto rejected like you mentioned, yikes.
I wanted to add that the following plugins are currently installed:

WordPress.com Stats
WP-Mail-SMTP
