Census does not publish a separate category for commercial cleaning and janitorial companies; these figures use NAICS 561720, Janitorial Services, the closest official industry. The count moved +0.9% between 2022 and 2023 in Michigan, against +0.7% nationally, so the field is not growing faster than the national market. Average annual pay in the industry is $29,172, below the $61,194 average across all Michigan industries, a useful proxy for how specialised and senior the workforce is.
The industry is concentrated in Oakland County, Wayne County and Macomb County, which together hold 40.9% 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.

What is a good time to contact businesses about cleaning?
When they move into new space, when occupancy increases after return-to-office changes, or when a building changes ownership. Those events reset vendor decisions.
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.
