Cold outreach

4.3%

lead rate on B2B cold emails sent to Market Research prospects in 2025, one of the ten highest by industry

Reader Note:: Tied on 4.3% with Mining & Metals in the report's lead-rate ranking, which runs from Public Safety at 5.4% down to Renewables & Environment at 3.1%. It is also one of two entries that do not fit the report's own explanation for the list — that these are industries with clear operational needs, like public safety, government and heavy industry. Higher Education at 3.5% is the other. The report's separate top 10 by share of email sent is a different set of industries entirely, with lead rates of 1.0-3.0%. Neither list gives the number of emails sent to this industry, so a high rate here may rest on a small volume. These are Sopro's own client campaigns rather than a market sample, and Sopro sells B2B prospecting services.
Evidence:: Observed behaviour
