commit: b67d552 - hire banner add for jobs on other sites (2014-04-23 08:56:43 -0400)
My experience is the success rate for guest posts is dropping lower and lower. I think one thing to touch on is the email subject. I think many bloggers have reached a point where there don't even check emails that are obvious guest post requests due to the huge % that are wasting their time and just after a link. Part of the trick could be ensuring your email gets read at all.
