69.5% of establishments in Chittenden County have fewer than 10 employees, below the 73.0% share for the United States. The 1,701 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 (18.8% of jobs) and retail trade (13.8% of jobs). Relative to the national mix, information (4.4% locally against 2.7% nationally) and educational services (4.0% locally against 2.8% nationally) stand out, which makes them natural first segments for outbound.
The number of establishments changed by −0.2% 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.

How to build a cold email campaign for Burlington
Pick segments from the data
Start with the sectors that are large or over-represented locally, such as health care and social assistance and retail trade, and only the ones your offer genuinely fits.
Filter by company size
Narrow to the size band your product serves; Chittenden County has 1,701 establishments with 10 to 249 employees. A tight list of well-matched accounts outperforms a long loose one.
Verify every address
Remove hard bounces, role accounts and stale records before anything is queued. Keeping hard bounces under 2 percent protects the domains everything else depends on.
Research each company
Look for a reason to write now: hiring, a new location, a leadership change, a launch. For Burlington prospects, local expansion news and job posts are usually the easiest signals to verify.
Send on protected infrastructure
Use secondary domains with SPF, DKIM and DMARC, warm them over three to four weeks, and keep each mailbox to 30 to 50 cold emails a day.

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.
What does Acqro do differently from other cold email tools?
Most cold email tools send the copy and list you provide. Acqro researches each target company's public signals first, such as hiring, funding, launches and leadership changes, and drafts each email from that evidence, with verification, authenticated sending domains, warmup and a unified reply inbox built in.
