How people at manufacturing companies answer cold email
The unit is the contact: one person who got a first cold email from one of 20 B2B campaigns on the Sales.co platform between March 6 and August 31, 2026, with replies counted up to October 9, 2026. The campaigns sold different products and services, so the tables show how these people answer B2B cold email in general. A positive reply is one where the person shows interest, asks a question, asks to be contacted later or refers a colleague.

| All industries | 336,257 | 2,830 | 975 | 0.29% |

One campaign supplied 6,814 of the 20,126 contacts (34%) and 7 of the 38 positive replies, a rate of 0.10%. The other 18 campaigns together got 31 from 13,312, or 0.23%.

By seniority
| Level | Contacts | Replied in person | Positive reply | Positive rate |
|---|---|---|---|---|
| C-level | 7,870 | 63 | 18 | 0.23% |
| VP | 2,248 | 12 | 2 | 0.09% |
| Director | 3,430 | 24 | 9 | 0.26% |
| Manager | 2,454 | 11 | 2 | 0.08% |
| Other levels | 4,124 | 32 | 7 | 0.17% |
This is why Sales.co says email alone underperforms in this vertical. A plant changes supplier at a renewal, a retool, an equipment failure or a quality problem, and a sequence cannot create those. Cold calls are an add-on, and for a maintenance supervisor a call works better than an email.

Who Sales.co emails when you sell into plants
| Segment | Who gets the email |
|---|---|
| Plant manager, VP Operations | Owns throughput and downtime. Responds to a number about a line. |
| Maintenance supervisor | The person a failure lands on. Worth calling rather than emailing. |
| Production engineer | Evaluates on the spec and wants a drawing or a sample first. |
| Director of procurement or sourcing | Knows the renewal date, sits in an office and reads email. |
| Quality manager | The route in when a defect or an audit finding has forced a second source. |
| Owner, shop under 100 staff | Buyer, estimator and often operator in one person. |
A manufacturer buying outbound for its own sales team gets the same tracks and pricing; the targeting depends on who it sells to. More on this vertical: the Sales.co manufacturers page.
Lists the campaigns are built from
| List | Contacts | Used for |
|---|---|---|
| Companies Using SAP | 38,000 | ERP-based targeting. If your product plugs into an SAP shop, the stack is a cleaner filter than an industry code. |
| Construction Lists | 376,800 | For building products and site equipment, where the buyer is a contractor rather than a plant. |
| General Contractors | 52,800 | The same case, narrowed to the firm that specifies and orders materials on a job. |
| Trucking Companies | 118,000 | Carriers and fleets. They buy from manufacturers and they move what plants make. |
| Hardware Startups | 4,788 | Early-stage hardware buyers choosing a contract manufacturer, a component supplier or tooling for the first time. |
There is no manufacturers list. A plant list is built to order inside the engagement. These lists sit next to it.
