A whole bunch of PR newbies ask this question every day - did you get my press release? Either their bosses are desperate for coverage or they need to report back to a client with outreach details.
This question irks many journalists. These same journalists get hundreds of emails a day. Many of them irrelevant and poorly targeted, so being followed up for a release that they would never cover is tiresome.
I spoke to a journalist yesterday and he was trying to get some features done but said that every two minutes he is getting a PR call. Potentially an exaggeration, but I am not a journalist so I'll take his word for it.
