Understanding Each Email Metric (In Depth)
To run successful email campaigns, it’s not enough to just send emails and hope for the best. You need to understand what each metric means, what affects it, and how to improve it. Here’s a deep dive into the most critical email marketing metrics for online stores:
1. Open Rate
Definition:
The percentage of recipients who opened your email, calculated as:
Open Rate = (Number of Opens / Number of Delivered Emails) x 100
Industry Average (Ecommerce): 30–35%
Good Performance: 35%+
Top Performers: 40%+
What Impacts Open Rate:
-
Subject line relevance & urgency
-
Personalization (e.g., “Hey [First Name]”)
-
Preview text effectiveness
-
Sender name (brand trust)
-
Send time and day of the week
-
Inbox deliverability (spam filters)
Tips to Improve Open Rate:
-
Use A/B testing on subject lines (emojis, questions, urgency)
-
Personalize the preview text and sender name
-
Clean inactive subscribers regularly
-
Avoid spammy phrases (e.g., “100% FREE”, “BUY NOW”)
-
Optimize send time with behavior-based timing
2. Click-Through Rate (CTR)
Definition:
The percentage of recipients who clicked at least one link in your email:
CTR = (Total Clicks / Total Delivered Emails) x 100
Industry Average: 2.5–3%
Good Performance: 3%+
Excellent Performance: 4–6%+
What Impacts CTR:
-
Email layout and design (mobile responsiveness)
-
Clarity of CTAs (call-to-actions)
-
Link placement and quantity
-
Relevance of product/content to the recipient
-
Visuals: buttons, product images, banners
Tips to Improve CTR:
-
Use buttons instead of hyperlinked text
-
Feature 1–2 primary CTAs only
-
Include dynamic product recommendations
-
Make it scannable (headlines, short paragraphs, bullet points)
-
Segment by customer behavior (e.g., “browsed but didn’t buy”)
3. Click-to-Open Rate (CTOR)
Definition:
The percentage of people who clicked on your email after opening it:
CTOR = (Clicks / Opens) x 100
Industry Average: 8–12%
Target Performance: 10%+
High Performance: 12–18%
Why CTOR Matters:
Unlike CTR, CTOR isolates how effective your content was once the user opened the email. It eliminates the impact of subject lines and deliverability and focuses only on content engagement.
What Impacts CTOR:
-
Relevance of content to the audience
-
Position and clarity of CTAs
-
Use of rich media (GIFs, product images, videos)
-
Mobile design and UX
Tips to Improve CTOR:
-
Match content to subject line expectations
-
Place the CTA above the fold
-
Use segmented product content (based on past purchases or browsing)
-
Experiment with interactive email elements (image carousels, buttons)
4. Conversion Rate
Definition:
The percentage of email recipients who completed a desired action (e.g., made a purchase, signed up):
Conversion Rate = (Number of Conversions / Number of Delivered Emails) x 100
Ecommerce Average: 1.5–2%
Excellent Performance: 3–5% (especially for automated flows)
What Impacts Conversion Rate:
-
Landing page speed and UX
-
Product offer relevance (price, timing, personalization)
-
Checkout friction (guest checkout, too many steps)
-
Discounts or scarcity (limited-time deals, social proof)
Tips to Improve Conversion Rate:
-
Use urgency: countdown timers, flash sales
-
Offer cart recovery discounts
-
Include product reviews and trust badges
-
Reduce form fields at checkout
-
Ensure the landing page matches the email offer exactly
5. Unsubscribe Rate
Definition:
The percentage of recipients who unsubscribe after receiving an email:
Unsubscribe Rate = (Unsubscribes / Delivered Emails) x 100
Average: 0.1–0.2%
Cause for Concern: 0.3%+
What Impacts Unsubscribes:
-
Over-emailing or poor frequency control
-
Irrelevant or repetitive content
-
Poor mobile formatting
-
Surprising users (emailing without clear opt-in)
Tips to Reduce Unsubscribes:
-
Let users set preferences (frequency, interests)
-
Monitor engagement scores and pause inactive contacts
-
Always send value (tips, content, early access—not just promos)
-
Use smart segmentation to avoid batch-and-blast
6. Bounce Rate
Definition:
The percentage of emails that failed to deliver:
Bounce Rate = (Bounced Emails / Total Sent Emails) x 100
Types of Bounces:
-
Hard Bounce: Invalid or non-existent email address
-
Soft Bounce: Temporary delivery issue (e.g., full inbox, server error)
Healthy Bounce Rate: < 0.5%
Red Flag: > 1%
Tips to Reduce Bounce Rate:
-
Use double opt-in for new subscribers
-
Regularly clean your email list
-
Remove addresses that haven't opened in 6+ months
-
Avoid purchased email lists entirely
7. Revenue per Email (RPE)
Definition:
Total revenue generated from a campaign divided by the number of emails sent:
RPE = (Revenue from Email / Total Emails Sent)
Average Range (ecommerce): $0.12 – $0.34
Top Performing Brands: $0.40 – $1.00+
What Affects RPE:
-
Product pricing and margin
-
Campaign timing (e.g., Black Friday vs. midweek)
-
Email segmentation
-
Use of upsells, bundles, and cross-sells
Tips to Increase RPE:
-
Focus on automation flows (welcome, cart abandon, win-back)
-
A/B test discount strategies (fixed amount vs % off)
-
Upsell high-value or repeat products
-
Send targeted offers based on browsing history

What Influences Email Benchmarks for Online Stores?
Email benchmarks don’t exist in a vacuum. Two online stores in the same industry might see very different results based on how well they handle certain influencing factors. Below is a comprehensive guide to the 12 most impactful variables that affect your email open rates, CTRs, conversions, and revenue per email.
1. List Quality and Hygiene
Why It Matters:
Your list is your foundation. If it’s full of unengaged users or invalid addresses, your performance will suffer—and you’ll hurt deliverability across the board.
Key Issues:
-
Purchased or scraped lists
-
Inactive subscribers (no opens in 90+ days)
-
High bounce rates
Best Practices:
-
Use double opt-in for new sign-ups
-
Clean your list every 3–6 months
-
Segment based on engagement (active vs inactive users)
2. Audience Segmentation
Why It Matters:
Sending the same email to your entire list is outdated. Segmentation allows you to send more relevant, higher-converting emails.
Common Segments:
-
Purchase history (bought X, suggest Y)
-
Geographic region (timezone, language)
-
Engagement level (active vs cold leads)
-
Behavioral triggers (abandoned cart, browse, etc.)
Best Practices:
-
Start simple: split new vs returning customers
-
Use dynamic blocks to personalize product offers
-
Use behavioral data from your ecommerce platform or ESP
3. Email Frequency and Cadence
Why It Matters:
Sending too many emails increases unsubscribe rates. Sending too few hurts engagement and revenue.
Common Mistakes:
-
Emailing every day without personalization
-
Not adjusting frequency based on engagement
-
Ignoring seasonality or customer lifecycle
Best Practices:
-
Use frequency caps (e.g., 1 promo per 48 hrs)
-
Let users set their email frequency preferences
-
Prioritize transactional and behavioral emails over campaigns
4. Send Time and Day
Why It Matters:
The best message in the world means nothing if it’s buried under 20 others in the inbox.
What Influences Optimal Timing:
-
Audience location (timezone)
-
B2C vs B2B (weekends vs weekdays)
-
Product type (impulse vs research-heavy)
Best Practices:
-
Test your send times (early AM vs evening)
-
Use predictive send time optimization (offered by Klaviyo, Mailchimp, etc.)
-
Consider behavior-based timing (e.g., 30 mins after browse)
5. Subject Line and Preview Text
Why It Matters:
These two elements determine whether your email gets opened—period.
Tips for High-Performing Subject Lines:
-
Use personalization (e.g., “Hey Sarah, your cart’s waiting”)
-
Add urgency or curiosity (“Back in stock — but not for long!”)
-
Keep it under 50 characters for mobile
Best Practices:
-
A/B test every campaign subject line
-
Use emojis carefully (can increase or decrease open rates based on audience)
-
Make preview text support and extend the subject line, not repeat it
6. Email Design and Layout
Why It Matters:
Visual presentation impacts CTR and CTOR. A cluttered or broken layout can sink engagement.
Key Design Factors:
-
Mobile responsiveness
-
CTA clarity and contrast
-
Load time and image optimization
Best Practices:
-
Use mobile-first, responsive templates
-
Keep designs clean and scannable
-
Use a single, bold CTA early in the email (“Shop Now”)
7. Personalization and Dynamic Content
Why It Matters:
Generic emails perform worse. Personalized content leads to higher engagement and revenue per email.
Ways to Personalize:
-
First name greeting
-
Location-based offers
-
Product recommendations based on behavior
-
“You left this in your cart” reminders
Best Practices:
-
Use dynamic product blocks (available in most ecommerce ESPs)
-
Customize content by gender, size, or product category when possible
-
Track behavior like wishlisting or page views
8. Automation and Triggered Emails
Why It Matters:
Automated flows (abandonment, welcome, browse recovery) consistently outperform standard campaigns across all benchmarks.
Key Flows:
-
Welcome series
-
Abandoned cart
-
Back-in-stock
-
Post-purchase
-
Win-back / re-engagement
Best Practices:
-
Build and optimize your core flows first
-
Personalize each step based on customer status
-
Monitor flow drop-off and performance at each email step
9. Product Types and Pricing Strategy
Why It Matters:
Benchmarks vary by product category and average order value (AOV).
Trends by Product Type:
-
Impulse buys (under $50): Higher conversion rates
-
Luxury or niche items: Lower CTRs, longer decision windows
-
Subscriptions: Higher long-term revenue per email, but lower initial conversions
Best Practices:
-
Match offer types to price point (e.g., bundle discounts for low-AOV items)
-
Use trust-building content for expensive or high-involvement purchases
10. Deliverability and Sender Reputation
Why It Matters:
Your benchmark performance is only possible if your emails land in the inbox—not the spam folder.
Factors That Impact Deliverability:
-
High complaint or bounce rates
-
Poor IP/domain reputation
-
Inconsistent sending volume
Best Practices:
-
Use SPF, DKIM, and DMARC authentication
-
Avoid spammy formatting (ALL CAPS, too many links)
-
Warm up new IP addresses gradually
-
Monitor your domain on tools like Google Postmaster Tools
11. Device and Email Client Usage
Why It Matters:
Different devices and email clients display your emails differently—and user behavior changes by device.
Key Data Points:
-
70–80% of ecommerce emails are opened on mobile
-
Apple Mail Privacy Protection (AMPP) affects open rate tracking
-
Gmail users tend to prefer image-rich layouts
Best Practices:
-
Design mobile-first and test on major clients
-
Focus more on click and conversion rates than open rates (due to AMPP)
-
Use concise, tappable CTAs for mobile users
12. Brand Loyalty and Customer Lifecycle Stage
Why It Matters:
A loyal customer will open and act on more emails than someone who barely knows you.
Lifecycle Stages:
-
New subscriber
-
First-time buyer
-
Repeat buyer
-
Churn-risk user
-
Lapsed customer
Best Practices:
-
Use lifecycle segments to deliver relevant content
-
Treat first-time customers differently than VIPs
-
Gradually re-introduce offers to lapsed users (win-back campaigns)

Final Thoughts: Don’t Just Measure—Optimize
Tracking email marketing KPIs is not the goal—optimization is.
You could have beautiful charts and data dashboards, but if you aren’t using that information to refine your campaigns, you’re not growing. The highest-performing ecommerce brands don’t settle for industry averages—they treat benchmarks as starting points, and their analytics as a roadmap for optimization.
Here’s how to turn tracking into transformation:
1. Benchmarking is Not a Destination, It’s a Diagnostic Tool
Benchmarks help you understand where you stand—but they don’t tell you why you're performing at that level or what to do next.
For example:
-
A 2% CTR isn’t inherently “bad,” but it might indicate your CTAs or design need refinement.
-
A high unsubscribe rate doesn’t mean “email doesn’t work”—it means segmentation or content relevancy needs improvement.
-
A high open rate but low CTR means your subject line works, but your email body doesn't deliver value.
Use benchmarks as a guidepost, not a final grade.
2. Optimization = Controlled Experiments + Iteration
You can’t optimize what you don’t test. Ecommerce brands should be running A/B tests regularly across all aspects of their email marketing.
Where to run A/B tests:
-
Subject lines (urgency, personalization, questions, emojis)
-
Send times (morning vs evening, weekday vs weekend)
-
CTA copy and placement
-
Number of products featured
-
Email layout (single-column vs grid)
-
Discount type (% off vs $ off)
Golden Rule: Test one variable at a time, measure the results, and apply learnings to future campaigns and flows.
Don’t stop testing once you hit “good” performance. The market evolves, and so do customer expectations.
3. Prioritize High-Impact Optimization Opportunities
Not all emails are created equal. Some emails—like automated flows—can generate more revenue over time than one-time campaigns.
Focus on optimizing your:
-
Abandoned Cart Flow – test discounts, product images, send times
-
Welcome Series – test how you introduce your brand and incentivize first purchase
-
Browse Abandonment Flow – test whether showing exact browsed products or related items performs better
-
VIP/Loyalty Campaigns – test offer types, product categories, personalization
80/20 Rule for Email Optimization:
Spend 80% of your time optimizing automated flows and your top campaigns, and 20% creating new sends.
4. Use Tools That Turn Data Into Action
Use the right tools that not only collect data, but enable smart decisions:
Goal | Tools |
---|---|
Identify low-performing subject lines | A/B testing in Klaviyo, Mailchimp, Omnisend |
Track email revenue by flow/campaign | Revenue dashboards in ESP, GA4 eCommerce |
Spot friction in landing pages | Hotjar, Microsoft Clarity, Shopify Session Replay |
Understand user behavior | Segmentation + engagement scoring tools |
Predict customer value | Klaviyo Predictive LTV, RFM models |
Pro Tip: Don’t just look at email metrics. Evaluate end-to-end journeys—from inbox to checkout.
5. Turn KPIs into Continuous Improvement Workflows
It’s not about massive overhauls—it’s about steady iteration. Set a recurring cycle:
Frequency | Optimization Task |
---|---|
Weekly | Review metrics from all campaigns and flows |
Bi-weekly | A/B test subject lines or content |
Monthly | Deep dive into top vs low-performing segments |
Quarterly | Refresh creative templates, update automations, prune cold subscribers |
Annually | Redesign your core flows based on customer feedback & LTV data |
Use a feedback loop:
-
Measure →
-
Analyze →
-
Test →
-
Implement →
-
Re-measure
6. Align Optimization With Business Goals
Your email optimization should support larger growth targets, not just vanity metrics.
For example:
-
Want to increase AOV? Focus on upsell/cross-sell automations.
-
Want more repeat buyers? Optimize post-purchase and loyalty sequences.
-
Want lower CAC? Improve welcome flow conversions and reduce unsubscribes.
-
Want to retain VIPs? Segment and customize high-LTV campaigns.
Email is not an isolated marketing channel—it’s a growth engine.
7. Optimization is a Culture, Not a Task
The best ecommerce email teams don’t treat optimization as a checklist item—they make it a mindset.
They:
-
Encourage curiosity over complacency
-
Track progress, not perfection
-
Celebrate small wins (e.g., +0.3% CTR = 300 more buyers if you have 100K subscribers!)
-
Build a culture of continuous improvement
Make optimization part of your team language: "What did we learn from this send?" should be a standard question after every campaign.
Final Optimization Checklist
Use this final checklist before publishing or iterating on any campaign:
-
Does the email match the subject line and preview text expectations?
-
Is the CTA clear, clickable, and above the fold?
-
Is the content segmented and relevant to the audience?
-
Have I tested this version vs an alternative?
-
Does the landing page continue the story from the email?
-
Have I reviewed this email’s performance 48h and 7d after send?
-
Have I tagged or documented key learnings?
Last Word
You can’t scale what you don’t optimize.
Data is your compass. Testing is your vehicle. And optimization is the engine that turns your email channel from a cost center into a reliable profit driver.
Start small. Be consistent. And always improve.
