The fault (if you consider it a fault) is in the Verizon SPAM filter. SPAM filters use various algorithms to decide what is SPAM and what isn't. Few algorithms are perfect.
One solution is to use
http://www.tinyurl.com/ to convert your original URL into something shorter. For instance, here's the tiny URL link to my website's TV gallery:
http://tinyurl.com/9fasfgc
I don't use Verizon mail, so I can't check whether the tiny URL substitute is also flagged as SPAM. You could check that by emailing yourself a tiny URL.
Another alternative would be to contact Verizon and ask them to "white flag" links to VK so that they aren't trapped by the filter, but that would be up to them.
