74.1% of establishments in Washington have fewer than 10 employees, above the 73.0% share for the United States. The 51,019 establishments with 10 to 249 employees are where most B2B lists should start: large enough to have a budget and a defined buyer, small enough that an owner or department head still makes the call and reads their own email.
By employment, the largest sectors are health care and social assistance (16.3% of jobs) and retail trade (11.1% of jobs). Relative to the national mix, information (5.3% locally against 2.7% nationally) and management of companies and enterprises (4.4% locally against 2.8% nationally) stand out, which makes them natural first segments for outbound.
The number of establishments changed by +0.1% between 2022 and 2023, slower than the +0.8% change for the United States. New and growing businesses are the accounts most likely to be choosing vendors for the first time, so pair that list with research on hiring, new locations and leadership changes before writing a single email.

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.
