How do B2B and B2C metrics differ?

If you're comparing your B2B email metrics to a benchmark study built on ecommerce retailers, you're going to feel bad for no reason. B2B and B2C email audiences behave very differently, and what looks like "poor" performance in one context is perfectly normal in the other.
Open rates
B2B emails tend to land in corporate inboxes filtered by IT-managed security gateways (like Proofpoint or Mimecast). These gateways often pre-scan emails, which can artificially inflate open rates (link prefetching) or suppress them (images blocked by default). Corporate environments also read email more slowly: a professional might batch-process their inbox twice a day rather than checking constantly.
B2C audiences, especially on consumer devices, tend to show higher raw open rates and faster engagement. They also have higher volatility: a great subject line gets opened immediately, a mediocre one gets ignored.
Click rates
B2B emails with a single clear CTA often outperform B2C in click-to-open rate because the audience has more intent when they open. If they opened a "see our pricing" email, they probably want to see pricing. B2C click rates vary more widely by email type: a promotional discount drives high clicks, an informational newsletter drives low ones.
Complaint and unsubscribe rates
B2B audiences are less likely to hit "report spam" and more likely to just stop reading. That means B2B complaint rates tend to look better, but the real disengagement is often hidden in the inactive segment. B2C audiences complain more freely, so the complaint rate is a more reliable signal of dissatisfaction.
Bounce rates
B2B lists have higher hard bounce rates naturally, because corporate email addresses go dead when employees leave companies. Role-based addresses (sales@, info@, support@) are also common in B2B lists and tend to have poor engagement. B2C hard bounce rates should be close to zero if your acquisition practices are good.
The practical takeaway: use industry-specific benchmarks when you have them, and weight your own historical trend higher than any benchmark. If you want to understand what engagement decay looks like in your specific context, track your own baseline over 6-12 months.
