Can I use door hangers instead of postcards for a BLITZ package?

A BLITZ only involves postcards because you're BLITZing a neighborhood with postcards, a door hanger BLITZ would be ordering door hangers and hanging them after you send a postcard BLITZ. Pro Tip: Send postcards, and then get door hangers designed that look just like your postcards and hang them shortly after the cards are delivered.
