This is a pretty broad question -- what are you looking for specifically on the PR front?
You get what you pay for. There are a million and three press release apps that are just spam-generators. They don't actually do what you would like.
Instead, try something like HARO or contacting journalists in your industry to establish a relationship.
Happy to help or field more questions, just schedule a call.
Sorry so should know that :)
I didn't mean where to post I actually meant apps like PR Genie, Robin8, HARO etc -- platforms that make reaching out to reporters etc easy....really any place to build lists without having to do manually. Does anything exist that I haven't heard of that makes finding these folks easier
