Census does not publish a separate category for public relations agencies; these figures use NAICS 541820, Public Relations Agencies, the closest official industry. The count moved −4.3% between 2022 and 2023 in Illinois, against +0.1% nationally, so the field is not growing faster than the national market. Average annual pay in the industry is $103,429, above the $72,398 average across all Illinois industries, a useful proxy for how specialised and senior the workforce is.
The industry is concentrated in Cook County, DuPage County and Sangamon County, which together hold 87.2% of the state's establishments. For a firm selling into the same market, that concentration also shows where buyers already have the most vendors to choose from, and where a researched, specific first email matters most.

How do PR agencies win clients with cold email?
Reference something newsworthy the prospect has done or is about to do, such as a funding round, launch or leadership hire, and suggest a specific story angle. That demonstrates media judgement immediately, which is what buyers are paying for.
Who hires a PR agency?
Founders and CEOs at growth-stage companies, CMOs or heads of marketing at established companies, and heads of communications where that role exists.
Is cold email legal in the United States?
Yes. The federal CAN-SPAM Act permits commercial email to business contacts without prior consent, provided the message identifies the sender accurately, uses a truthful subject line, includes a valid physical postal address and a working opt-out, and honours opt-out requests promptly. CAN-SPAM applies in every state and preempts most state commercial email laws, except provisions aimed at falsity or deception. This is general information, not legal advice.
