@gargron yes. Welllllll you really just need to get a list of names and email addresses, and the shoot the human beings on the other side an email. I don't do publicity for work, and I'm not a marketing genius. My focus is on content creation and copywriting with light marketing on the side.
You need a person whose job is doing the thing, or a firm, but they'll make some demands about analytics, and reach, and message.
