Email marketing statistics

Email remains one of the best-performing channels in B2B. These figures show why, and where the real gain lies: relevance, automation and segmentation, not volume.

What do these figures mean for Belgian B2B companies?

The common thread in the email figures is consistent: email pays off, but not by sending more. The companies that get the most out of it send less but more relevant email, segment their list, and automate follow-up so no lead goes cold.

That automated emails make up barely 2% of volume but deliver almost a third of revenue says enough: the gain lies in timing and relevance, not reach. Triggered emails get more than three times the clicks of an untargeted scheduled campaign.

For B2B with long sales cycles, that’s even more true. A well-thought-out email flow that warms up leads until they’re ready for a conversation delivers more than a weekly newsletter blasted to your entire list. Steer on customers and revenue, not on open rates that are skewed anyway by privacy measures.

Frequently asked questions

Are open rates still a reliable statistic? +

Less than they used to be. Since Apple Mail Privacy Protection (2021) automatically loads images, open rates are artificially inflated. Steer instead on clicks, replies and ultimately inquiries.

What's a good ROI for email marketing in B2B? +

The often-cited 36 euros per euro is an average across all sectors. For B2B, what matters most is whether email moves qualified leads toward a sales conversation, not the exact ROI figure.

What's a realistic click rate for B2B emails? +

Expect around 1 to 2 percent on your full volume sent. The click-to-open rate for business emails sits around 5%. If your click rate is structurally below that, look at your subject lines, segmentation and relevance.
