Cold outreach

3.0%

lead rate on B2B cold emails sent to Construction prospects in 2025

Reader Note:: This industry appears in the report's top 10 by share of cold email sent, not by performance: it took 5.1% of Sopro's 2025 sends, third largest, and slipped one place on that ranking from 2024. At 3.0% it has the highest lead rate in that list, which runs down to 1.0%, but still sits below the 3.1-5.4% of the industries heading the report's separate lead-rate ranking. These are Sopro's own client campaigns rather than a market sample, and Sopro sells B2B prospecting services.
Evidence:: Observed behaviour
Vendor interest:: High — This comes from a company with a commercial interest in this market, so it is not a neutral source.
Sample:: Survey: 442 senior B2B decision-makers (self-reported). Also draws on ~126M emails / 25M multichannel touchpoints and a 650,000-email 2025 send corpus for the message-pattern analysis, plus 2025 campaign benchmark data (lead rates by company size/industry).
