Email Marketing Metrics to Track for Better Campaign Results

Email marketing metrics to track should be the starting point for any business serious about improving their B2B outreach. Without them, you’re just guessing.

For many SME decision-makers, email campaigns are launched with the right intentions — but when results come in, they’re either misread or ignored altogether. You might see open rates, clicks, or unsubscribes in your dashboard… but what do they really mean? And more importantly — what should you do next?

This post breaks down the essential metrics you need to monitor to make smarter, more profitable decisions with your email campaigns. Whether you’re using purchased B2B data or nurturing existing leads, understanding these numbers helps you spot what’s working, fix what isn’t, and drive better outcomes.

No jargon, no fluff — just practical guidance to help your emails perform better.

Why Tracking the Right Email Metrics Matters

Understanding the email marketing metrics to track is more than a reporting exercise — it’s the foundation for smarter, more profitable campaigns.

Avoid Guesswork

Without metrics, you’re relying on gut instinct. That might work once or twice, but it’s not sustainable. Tracking the right numbers gives you clarity: what’s working, what’s not, and where to focus next.

Protect Your Budget

Time and money are wasted on underperforming campaigns — often because no one spotted the warning signs. Metrics help you catch issues early, whether it’s a subject line that’s falling flat or a list that’s no longer delivering.

Build Better Campaigns Over Time

Every metric tells a story. Over time, patterns emerge — you’ll learn what your audience responds to, when they’re most engaged, and how to keep improving. This isn’t just about one campaign. It’s about building momentum.

In short: if you’re not measuring, you’re not marketing. You’re just sending.

The Core Email Metrics You Should Be Watching

Knowing which email marketing metrics to track helps you focus on what actually drives results — and avoid chasing vanity numbers that don’t move the needle.

Open Rate – Who’s Noticing Your Message?

Open rate shows how many people opened your email compared to how many received it.

• What it tells you: How effective your subject line, sender name, and timing are

• What to watch: Drops could signal poor relevance or deliverability issues

• A note on accuracy: iOS privacy updates can inflate open rates — focus on trends, not individual figures

Click-Through Rate (CTR) – Who’s Taking Action?

CTR measures how many recipients clicked a link in your email.

• Why it matters: It shows engagement and whether your offer, layout, or CTA worked

• Low CTR? Consider simplifying your message, testing different CTAs, or improving layout clarity

Bounce Rate – Is Your Data Doing Its Job?

Bounce rate shows how many emails failed to deliver.

• Hard bounces: Permanently undeliverable (e.g., invalid addresses)

• Soft bounces: Temporary issues (e.g., full inbox or server problem)

• What it signals: Issues with data quality, list age, or segmentation — especially relevant if you use purchased data

Unsubscribe Rate – When to Be Concerned

Every campaign loses a few contacts — but patterns matter.

• What’s normal: A small, steady unsubscribe rate is expected

• Red flags: Sudden spikes may mean poor targeting or irrelevant messaging

• Fix it: Check your segmentation and review your email frequency

Conversion Rate – Measuring Actual Outcomes

This is the ultimate goal: how many recipients took the desired action.

• Define what counts: Booking a call, downloading a guide, making a purchase — it’s your key success indicator

• Why it matters most: Opens and clicks are good… but conversions pay the bills

• Tip: Make sure you’re tracking this end-to-end using UTM tags or CRM feedback

Advanced Metrics to Watch (Optional but Useful)

Once you’ve nailed the core email marketing metrics to track, there are a few additional stats that can give deeper insights — especially if you’re running higher-volume or more complex campaigns.

Response Time – How Quickly People Engage

• Measures how soon after sending recipients open or click

• Fast responses often indicate high relevance or timing alignment

• Helps you identify peak engagement windows for future sends

Device and Platform Performance

• Breakdown of mobile vs desktop engagement

• Can influence design decisions (e.g., mobile-first layouts, shorter subject lines)

• Helps optimise for the most-used platforms among your audience

Forward or Share Rate

• Indicates if your content was engaging enough to be passed along

• Rare in cold B2B campaigns, but valuable when targeting warm lists or referrals

• Can highlight strong content or offers worth repeating

Heatmap or Scroll Depth (if available)

• Visualises how recipients interact with your email layout

• Useful for optimising CTA placement and reducing drop-off

• Available through some email platforms, worth checking if you have access

Interpreting Your Metrics: Turning Numbers Into Action

Tracking email marketing metrics to track is only useful if you know what to do with the results. Metrics are signals — and your job is to translate them into better decisions.

Don’t Panic Over One-Offs

A single bad result doesn’t mean your strategy is broken. Look for patterns over time. Consistent dips are more telling than isolated underperformance.

Understand Cause and Effect

• Low open rates? Look at subject lines and timing

• Good opens but low clicks? Focus on your content and CTA

• High bounces? Time to review your data source and list hygiene

Use Trends to Guide Tests

Metrics should shape your next move. See open rates slipping? Run a subject line A/B test. Notice clicks dropping? Try a new layout or clearer call-to-action.

Avoid Vanity Metrics

It’s easy to obsess over opens or clicks — but if those don’t lead to conversions, they’re just noise. Focus on outcomes that match your campaign goals.

Setting Realistic Benchmarks and Goals

Not every campaign needs to break records — but every campaign should have a clear goal. To get the most from the email marketing metrics to track, you need context.

Industry Benchmarks Are Just a Guide

• Average open rates for B2B sit around 15–25%

• Click-through rates are often below 5%

• But these vary by sector, audience, and campaign type

Benchmarks help, but they’re not gospel — what matters is how your campaigns perform over time.

Compare Against Your Own Results

The most useful benchmark is your last campaign. If your open rate improved 4% after tweaking your subject line, that’s a win — even if you’re still below the “industry average.”

Let Your Goals Shape the Metrics That Matter

• Brand awareness? Focus on opens and shares

• Lead generation? Prioritise clicks and conversions

• List quality? Keep an eye on bounce and unsubscribe rates

Define success before you hit send — and track accordingly.
