Email marketing is widely used across construction, architecture and property businesses. But interpreting the results is not always straightforward.
Open rates and click-through rates are easy to access, but harder to assess. Many firms compare their results to generic benchmarks and assume they are underperforming. In practice, construction email marketing behaves differently to most other sectors.
What matters is understanding what the numbers are actually telling you.
Benchmarks are a reference, not a target
UK email marketing benchmarks typically show average open rates of around 35 to 40 percent, with click-through rates of roughly 2 to 3 percent.
Construction and architecture firms often fall within a slightly broader range. Open rates may sit anywhere between 30 and 45 percent, while click-through rates are often between 2.5 and 4 percent. Click-to-open rates commonly land in the high single digits or low teens.
These figures are useful for context, but they are not performance targets. They do not, on their own, indicate whether an email campaign is effective.
Why early results rarely reflect reality
For businesses new to email marketing, the first few campaigns should be treated cautiously.
Email platforms take time to understand how recipients interact with content. Engagement tends to fluctuate early on, and list quality has a significant influence on results. At this stage, the data is indicative rather than conclusive.
Open rates are also less reliable than they once were. Apple Mail Privacy Protection means some emails are recorded as opened even when they are not actively read. As a result, high open rates can be misleading.
Metrics such as click-through rate, click-to-open rate, website visits and direct replies often provide a more useful picture.
How email functions in the construction sector
Email marketing in construction is rarely transactional.
It is typically read by senior professionals and used as a way to maintain awareness rather than prompt immediate action. Many recipients read emails without clicking through. This does not mean the content has been ignored.
Emails can reinforce credibility, demonstrate consistency and keep a business visible over time. Their influence is often indirect and long-term, particularly in relation to tenders, referrals and repeat work.
List quality matters more than scale
Smaller, well-maintained mailing lists usually perform better than larger ones.
Lists made up of past clients, consultants, developers and trusted contacts tend to achieve stronger engagement. Recognition of the sender plays a significant role. If recipients do not immediately recognise the business, engagement and deliverability both decline.
In this context, growth in list size is less important than relevance.
Understanding click-through rates
Construction email campaigns often show relatively modest click-through rates alongside healthy open rates. This is normal for the sector.
Content is usually informational rather than promotional. Readers may take in the information without needing to follow a link. A click-through rate of 2 to 4 percent can represent a good outcome, particularly when clicks come from relevant decision-makers.
The quality of engagement is generally more meaningful than volume.
What effective practice tends to look like
Most construction firms benefit from a lower sending frequency.
Monthly or bi-monthly emails linked to genuine updates such as projects, insights, people or recognition tend to perform better than frequent campaigns. Sending more emails does not usually improve results.
Email marketing also works best as part of wider business development activity. It supports visibility and credibility, rather than replacing direct relationships or conversations.
Performance typically improves over time as patterns emerge, audiences are refined and consistency builds. Useful insight usually comes after several campaigns rather than one or two.
A more useful way to assess performance
Rather than focusing on headline metrics, it is often more helpful to ask:
- Are the emails reaching the right people?
- Are they being opened by relevant contacts?
- Are they generating occasional, meaningful engagement?
If so, the email marketing is likely serving its purpose.
In construction, effectiveness is usually measured over time, not per send.
