We never "bulk" , "blast" , "spam" or (whatever your term for it is) the media.
Reporters, editors, etc. are inundated everyday with "junk". Meaning press release that have nothing to do with what they report on. They get blasted by call centers with 18 year olds reading from canned scripts, their inbox gets filled up with worthless email (at least to them) and so on.
When we send your press release to a media outlet we want them to know it's from Rapid Press Release - and it's Relevant to what they report on. It makes their job that much easier and gets our clients the exposure they seek.
