How to sell to contractors by cold email
Updated November 6, 2026. Reply data read October 9, 2026; list counted September 3, 2026.
To sell to contractors by cold email, write to the owner, name a job type they do, and keep the ask small. In our data 87 of 12,547 real estate and construction contacts replied with interest (0.69%), more than twice the 0.29% average, though only 1 booked a meeting.
This page is for companies that sell materials, software, insurance or services to general contractors and builders. The numbers come from 336,257 contacts who got a first cold email from one of 20 Sales.co campaigns between March 6 and August 31, 2026, with replies read on October 9, 2026.

What happened when real estate and construction contacts got cold email
| Who got the email | Contacts | Replied in person | Positive replies | Booked meetings |
|---|---|---|---|---|
| Real estate & construction | 12,547 | 161 (1.28%) | 87 (0.69%) | 1 (0.008%) |
| All 20 campaigns | 336,257 | 2,830 (0.84%) | 975 (0.29%) | 143 (0.043%) |
87 positive replies led to 1 booked meeting, a low conversion to calls in these campaigns. We do not know why so few replies became meetings, so offer a reply in the thread and a call at a time they choose. The group also includes real estate companies, so a contractors-only send may land higher or lower.
How many contractors you can reach
The Census counted 254,630 building construction companies with paid staff in 2023 (Construction of buildings, NAICS 236), and specialty trades sit outside that number. Our list holds 40,849 contacts in all 50 states and DC, about 16% of that Census figure, counted September 3, 2026.
| State | Contacts on our list | Census: building construction companies |
|---|---|---|
| California | 7,074 | 29,852 |
| Texas | 4,752 | 16,334 |
| Florida | 3,269 | 19,051 |
| New York | 2,467 | 19,308 |
Who is on the list
31% of addresses are on free mail, the highest share of the four lists here that report one. Those addresses may include owner inboxes; we have not checked who reads them. 49.2% of records are tagged general contractor, 20.6% construction company and 18.8% contractor. Houston leads the cities with 1,115 contacts. Trades have their own lists: roofers, electricians, HVAC contractors and plumbers.
How to run it, step by step
- Pick one state and one kind of work. California alone has 7,074 contacts on the list, and a local reference helps.
- Clean the file first. With this much free mail, run it through the free list cleaner so typos and role inboxes come out before you send.
- Send a short first email that names the type of job and asks one question the owner can answer from a phone.
- Move the reply to a phone call at a time they choose. In our data 87 positive replies turned into 1 booked meeting, so plan how you follow up.
A worked example, with the numbers
This applies the positive reply rate above to the whole list and to one month of the $2,000 plan, with a 95% range around 87 positive replies from 12,547 contacts. It assumes the list behaves like the real estate and construction contacts in our campaigns, and three emails to each contact.
