What's a Good Email Open Rate for Manufacturing and Industrial Companies in 2026?

General marketing emails sent to manufacturing and industrial B2B contacts open at roughly 21-27% in 2026, in line with the broader B2B average — but manufacturing-specific cold outreach emails run notably higher, at 30-40%, and manufacturing has the highest click-to-open rate of any B2B sector tracked, at 14.82%.

Two Different Numbers, Two Different Email Types

• General marketing and newsletter emails to manufacturing contacts: roughly 21-27% open rate, tracking closely with the 20-25% open rate benchmark reported across B2B overall
• Manufacturing-focused cold outreach and sales prospecting emails: 30-40% open rate, reply rates of 2-3.5%, and meeting booking rates of 0.6-1.5%, according to 2026 cold email benchmark research focused specifically on the sector
• These are not interchangeable figures — a manufacturing marketing team benchmarking a newsletter against the 30-40% cold-outreach number is comparing against the wrong email type entirely

Why Manufacturing's Click Engagement Stands Out

Manufacturing has the highest click-to-open rate (CTOR) of any B2B industry tracked in 2026 benchmark data, at 14.82% — meaning that once a manufacturing recipient opens an email, they're more likely to click something inside it than a recipient in almost any other B2B sector. That's a meaningfully different signal from open rate alone, and 2026 benchmark guidance increasingly treats CTOR as the more trustworthy engagement metric for the reasons below.

Company Size Shifts the Numbers Further

Smaller manufacturers, under roughly 50 employees, respond to cold outreach at significantly higher rates — 42-55% opens and 4-7% replies — compared to enterprise manufacturers, who land at 25-38% opens and just 1.5-3% replies. A campaign targeting a mix of small and large manufacturing accounts should expect blended performance somewhere between those two bands rather than a single flat number.

Why Manufacturing's Inbox Behaves Differently

Manufacturing and other traditional industrial sectors tend to see lower daily email volume than sectors like SaaS or media, which means a given email faces less inbox competition. That's the likely driver behind manufacturing's comparatively strong reply and click engagement even where raw open rates aren't dramatically higher than the general B2B baseline — recipients who do open an email in a less-crowded inbox are more likely to actually read it before deciding whether to click.

The Apple Mail Privacy Caveat Still Applies

Like every open-rate benchmark in 2026, these manufacturing figures are inflated to some degree by Apple Mail Privacy Protection, which auto-loads tracking pixels for a large share of recipients regardless of whether a human actually reads the message. That's part of why CTOR and reply rate carry more weight than open rate alone in current benchmark guidance for this sector.

Bottom Line

Use 21-27% as the realistic open-rate benchmark for general marketing emails to manufacturing and industrial contacts, and 30-40% specifically for cold outreach — then weight CTOR (manufacturing's standout metric, at 14.82%) and reply rate more heavily than open rate alone when judging whether a campaign is actually working.
