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 −0.4% between 2022 and 2023 in California, against +0.1% nationally, so the field is not growing faster than the national market. Average annual pay in the industry is $108,266, above the $87,119 average across all California industries, a useful proxy for how specialised and senior the workforce is.

The industry is concentrated in Los Angeles County, Sacramento County and San Francisco County, which together hold 64.2% 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 many PR agencies are there in California?

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.
