The 2025 B2B Email Marketing Benchmarks You Need to Beat

Email may not be new, but it’s still one of the highest-performing channels in B2B marketing—when it’s done right. 

In fact, on average, email delivers the highest ROI of any channel at $36 return for every $1 spent (a return of 3,600%).

The problem? Most marketers aren’t sure what “right” even looks like anymore. Despite being considered one of the most important marketing channels, only 8% of B2B marketers said email was effective for lead generation in 2024.  

If you’re sending campaigns without clear performance benchmarks to compare against, you’re flying blind.

That’s why we’re breaking down the latest 2025 B2B email marketing benchmarks—and showing you how to blow past them with smarter outreach and better audience targeting.

Let’s dive in.

Why benchmarks matter more than ever in 2025

Inbox competition is at an all-time high. Between marketing emails, newsletters, event invites, and sales follow-ups, your prospects are drowning in messages.

So how do you know if your email is making an impact—or just adding to the noise?

That’s where industry benchmarks come in. B2B email marketing benchmarks provide a reality check on your performance, helping you:

• Diagnose underperforming campaigns
• Identify strengths to double down on
• Justify investment in better targeting or tools
• Set realistic goals for improvement
  

Without them, you risk comparing apples to oranges—or worse, making decisions based on gut feel rather than real data.

2025 B2B email marketing benchmarks (and what they really mean)

We’ve pulled benchmark data from trusted sources across the B2B space to give you a clear picture of where your campaigns should be.

These numbers can vary depending on your audience, content, and timing—but they serve as a solid baseline for evaluating performance.

5 reasons your B2B emails may be underperforming

Falling short of these B2B email marketing benchmarks? You’re not alone. Here are five common reasons B2B marketers miss the mark:

1. You’re emailing the wrong audience
   Generic lists and scraped contacts lead to low engagement and high bounces. Quality beats quantity—especially in B2B tech.
   
2. Your subject lines aren’t earning opens
   If your subject line isn’t compelling or relevant, your email won’t even get a shot. Try testing A/B testing different subject lines based on urgency, curiosity, or personalization.
   
3. Your content isn’t aligned with buyer intent
   B2B tech buyers don’t want fluff—they want clear value. Generic messaging or gated PDFs with no real takeaway are a fast track to unsubscribes.
   
4. You’re not segmenting or personalizing
   Sending one-size-fits-all messages to your entire list rarely works. Segmentation and customization are non-negotiable in 2025. In fact, research shows that segmented email campaigns bring in 760% more revenue than non-segmented ones.
   
5. You’re not learning from your data
   Too many teams “set it and forget it” with their email marketing campaigns. Reviewing engagement by persona, offer, or industry can reveal huge opportunities for improvement.

• Segment by buyer stage, not just job title
• Use plain-text emails for a personal feel
• Include clear, benefit-driven CTAs
• Regularly clean and validate your lists
• Repurpose top-performing emails across social or retargeting

And if list fatigue is creeping in or your internal database has gone quiet, that’s your cue to bring in ViB.
