Cold outreach to Construction companies

The construction project manager is focused on delivering projects on time and within budget. They respond to outreach that shows an understanding of common project delays, such as supply chain issues or labor shortages. Demonstrating awareness of these factors can make your outreach more compelling, as it speaks directly to their daily challenges.

Written and maintained by the SoloRiff team, who build outbound software and run outbound with it. The figures below are our own: we measured 564 construction company domains over public DNS on 2026-09-03. Last updated 2026-09-03.

What actually hurts

  • project delays
  • supply chain disruptions
  • labor shortages

The playbook

  1. 01

    Identify projects with delays

    Use platforms like ConstructConnect to filter for projects that are behind schedule. Look for projects that have reported delays due to material shortages or labor issues. This gives you a relevant context for your outreach, showing you understand their current struggles.

  2. 02

    Research key decision-makers

    Utilize LinkedIn to identify the project managers and procurement officers involved in these delayed projects. Focus on companies with a history of similar challenges. Personalizing your outreach to these individuals increases the likelihood of engagement.

  3. 03

    Craft a message about solutions

    Write an email that highlights how your solution can specifically address the issues of supply chain disruptions or labor shortages. Mention a relevant case study where your approach helped a similar company overcome these hurdles. This shows you have practical insights into their pain points.

  4. 04

    Follow up with a timely reminder

    If you haven’t received a response within a week, send a follow-up email referencing the specific project delay. Acknowledge their busy schedule and reiterate the potential benefits of your solution. Timing your follow-up can keep the conversation alive.

  5. 05

    Suggest a brief call

    In your follow-up, propose a 15-minute call to discuss their project challenges further. Offer a few specific time slots to make scheduling easier. This direct approach can prompt a response and lead to a productive conversation.

Can construction companies even receive your mail?

We measured the DNS of 564 construction companies, sampled evenly across company sizes, to see how many authenticate their own email. It matters in both directions: a domain that does not authenticate is a domain whose team is used to mail going missing — and if your own domain is in the gap, yours is the mail going missing.

1–10 employees
19.2%
11–50
23.7%
51–200
43.1%
201–1,000
60%
1,000+
73%

Publishes a DMARC policy of quarantine or reject — the domain actually asks receivers to act on failures.

The gap is the finding: 19.2% of 1–10-person companies against 73% of the largest — 54 points apart. Small companies are where the unauthenticated domains are, and small companies are who most cold outreach is aimed at.

Where does your domain sit?

Same three lookups, run live against your domain. Nothing is stored and nothing is emailed to you.

How this was measured

Company domains were sampled within employee-count bands, then queried over public DNS for SPF (TXT at the apex), DMARC (TXT at _dmarc.) and MX. One domain per company, deduplicated. Anyone can reproduce any single row of this with dig.

DKIM is deliberately absent. A DKIM key lives under a selector that cannot be enumerated from outside the domain, so a company with flawless DKIM under a name we did not guess would be counted as having none. That would measure our guess list, not the industry.

Domains with no MX record are excluded rather than counted as failures — parked and redirect-only domains would otherwise drag every figure down and make the result an artefact of the sample.

Sampled within bands, so this describes the population of companies, not of employees: a 10-person company counts once, as does a 10,000-person one. Each band is at least 60 domains; bands below that are not published. Figures are percentages of the sample, not of the whole industry, and we publish no company names — only counts.

Measured 2026-09-03. Re-measured monthly.

Questions

Why do construction project managers ignore outreach about software solutions?
Construction project managers often receive numerous outreach messages that lack relevance to their immediate challenges. If the outreach does not address specific issues like project delays or labor shortages, it is likely to be overlooked. A tailored approach that speaks directly to their current pain points can improve response rates.
What common challenges do construction project managers face?
Construction project managers frequently deal with issues such as project delays, budget overruns, and labor shortages. These challenges can stem from various factors, including supply chain disruptions and unforeseen site conditions. Understanding these pain points is crucial for anyone looking to engage with them effectively.
How can I demonstrate value to a construction project manager?
To demonstrate value, focus on how your solution can directly alleviate their most pressing challenges, such as reducing project delays or optimizing resource allocation. Providing specific examples or case studies relevant to their industry can help establish credibility and relevance.
What factors influence a construction project manager's decision-making?
A construction project manager's decision-making is influenced by project timelines, budget constraints, and the availability of skilled labor. They prioritize solutions that can enhance efficiency and mitigate risks associated with delays or cost overruns. Tailoring your outreach to these factors can make your proposition more appealing.
