Census does not publish a separate category for business telecom and VoIP providers; these figures use NAICS 517911, Telecommunications Resellers, the closest official industry. The count moved +15.3% between 2022 and 2023 in Michigan, against +14.7% nationally, so competition for the same buyers is growing faster here than elsewhere.
The industry is concentrated in Oakland County, Wayne County and Kent County, which together hold 43.7% 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.

Yes.

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.
