Direct Answer (Quick Summary)

Cold email still books calls with contractors when each email names a real problem in that business, such as no website, few reviews or no ads running, and asks for a short 15-minute call. Send from a warmed-up secondary domain, keep volume low per mailbox (under 35/day), follow up three to four times, and adhere strictly to CAN-SPAM requirements.

Is cold email legal in 2026?

In the United States, B2B cold email is legal under the CAN-SPAM Act if you: 1) Avoid deceptive header or subject lines; 2) Include a valid postal physical address; 3) Provide a clear opt-out link or unsubscribe reply method; and 4) Honor opt-outs within 10 business days. In the UK, PECR treats sole traders differently from corporations, so ensure commercial relevance. In Germany and the EU, GDPR generally requires verifiable business interest.

Infrastructure: domains, mailboxes, and deliverability

Never send cold outbound from your primary agency domain. Register 2–3 secondary domains (e.g. get[agency].com), configure SPF, DKIM, and DMARC records, warm them up for 14–21 days, and limit sends to 30–40 emails per inbox per day.

Template 1: The 'No Website / Competitor Arbitrage' Hook (Roofers)

Subject: quick question about {{city}} roofing Hi {{first_name}}, I was looking at roofing businesses in {{city}} and noticed {{company_name}} has solid reviews ({{rating}} stars) but no active website listed on your Google profile. Right now, {{competitor_name}} is taking about 400 monthly organic searches in {{city}} because their site ranks in the map pack. We build contractor sites that capture those calls.

Frequently Asked Questions

Is cold email legal?

In the US, B2B cold email is legal under CAN-SPAM if you use honest headers and subjects, include a postal address and an opt-out, and honour opt-outs within 10 business days. Rules are stricter in the UK for sole traders and in much of the EU.

Is cold email still effective?

Yes, when emails are short, personal and sent in low volumes from warmed-up mailboxes. Generic bulk sends mostly land in spam.

How many cold emails per day should I send?

Keep each mailbox to a modest daily volume and ramp up slowly over several weeks; spread larger volumes across several mailboxes and domains.

Is cold email better than cold calling for contractors?

They work best together: email shows you looked at the business, the call or text gets the answer. Many contractor owners respond faster to a call or SMS.

What should a cold email to a contractor say?

Name one specific problem you found, such as no website or few reviews, say what it costs them, and ask for a 15-minute call.
