Email deliverability - Important metrics to track
1. Email Delivery Success Rate
Your email delivery success rate shows how well your email verification efforts are paying off. It measures the percentage of emails that successfully land in recipients' inboxes, excluding those that bounce or get blocked. Keep in mind, "delivered" emails can include those sent to spam folders - not just inboxes.
Recent data highlights a concerning trend: about one in six legitimate, permission-based marketing emails never makes it to the inbox. This results in a noticeable drop in potential ROI [1][3].
What Delivery Rates Say About Your Email List
Delivery rates are a key indicator of your email list's health. Here's a quick breakdown:
| Delivery Rate | Status | Action Needed |
|---|---|---|
| 98-99% | Excellent | Stick with current practices |
| 85-97% | Good | Monitor and make adjustments |
| 70-84% | Needs Work | Start verifying your list |
| Below 70% | Critical | Clean your list immediately |
"If you could get those emails to the inbox and they performed like your other messages, you'd see a 20% lift in your email ROI" [2].
Tips to Improve Delivery Success Rate
- Remove hard bounces: Protect your sender reputation and boost deliverability.
- Use authentication protocols: Implement SPF, DKIM, and DMARC to validate your emails.
- Adopt double opt-in: Ensure new subscribers truly want your emails.
- Verify and clean your list regularly: This keeps your list fresh and reduces issues.
High bounce rates are a red flag for email deliverability. Aim to keep bounce rates below 2%. Anything above 5% suggests major problems with your list.
"If you don't remove hard bounces from your list and continue to send them emails, you will damage the reputation of your IP address which will create a problem for your deliverability long-term" [1].
Improving your delivery rate creates more opportunities for engagement and conversions, which directly boosts your ROI. Once you’ve nailed delivery success, the next challenge is getting recipients to actually engage with your emails.
2. Email Open Performance
Open rates are a clear indicator of how email verification can improve engagement. Since email lists naturally lose about 22.5% of their contacts each year, keeping your list clean is essential to accurately measure the return on investment (ROI) of your email campaigns.
Understanding Open Rate Metrics
Open rates show the percentage of delivered emails that recipients actually open. A higher open rate usually signals better engagement and healthier email lists. Here's a quick breakdown of what open rates can tell you about your list's condition:
| Open Rate Range | What It Means | Suggested Action |
|---|---|---|
| Above 25% | Strong list quality | Keep verifying regularly |
| 15-25% | Decent performance | Watch for signs of decline |
| 10-15% | Needs improvement | Clean your list immediately |
| Below 10% | Major problems | Perform a thorough verification |
How List Hygiene Affects Open Rates
Many email senders - 38.7% to be exact - often skip regular list maintenance. However, verified email lists typically see a 5-15% boost in open rates. Removing inactive or invalid contacts not only improves open rates but also enhances the overall effectiveness of your campaigns.
Ensuring Open Rate Accuracy
Privacy features, like Apple’s Mail Privacy Protection (MPP), can inflate open rate numbers. To get a more accurate picture, track trends over time and use additional engagement metrics. Comparing results before and after verifying your list can help you assess the true impact.
The Results of Verification
Email verification ensures your messages land in valid inboxes, which directly improves open rates. For instance, email strategist Dylan Redekop noted a 15% lift in open rates after implementing effective list-cleaning practices. Verified lists also tend to achieve up to 25% better deliverability, which translates into stronger open rates and more successful campaigns.
Higher open rates mean your content is reaching and resonating with more people. This not only increases the chances of conversions but also maximizes your ROI. Once you’ve improved your open rates, the next step is turning those opens into clicks and meaningful interactions.
3. Email Click Rates
Click-through rates (CTR) measure how effectively your email campaigns drive subscriber actions. While open rates show how many people see your emails, CTR highlights how many actually engage - making it a key metric for assessing ROI.
Industry Benchmarks and Performance
On average, click-through rates across industries sit at 2.62%. However, verified email lists often outperform this, as they target active and engaged subscribers. Comparing your results to these benchmarks can help gauge the value of email verification.
How List Quality Affects Click Rates
The quality of your email list has a direct impact on click performance. Here's how:
| List Quality Factor | Effect on Click Rates | ROI Benefit |
|---|---|---|
| Removing Invalid Addresses | 25% better delivery rates | Reduced engagement costs |
| Focusing on Active Subscribers | Doubled engagement levels | Higher conversion rates |
| Using Verified Domains | Fewer emails flagged as spam | Better ROI outcomes |
Tracking ROI from Email Verification
To measure the effect of email verification on CTR:
- Establish a baseline: Record CTR before cleaning your list.
- Monitor changes: Track improvements after verification.
- Analyze costs: Assess changes in engagement expenses.
- Maintain quality: Keep tracking performance to ensure ongoing success.
Steps to Improve Performance
Boost your results with these strategies:
- Use verified data to segment your audience more effectively.
- Deliver targeted content to the most engaged groups.
- Regularly clean your list to keep engagement levels high.
Turning Clicks Into Results
Keeping your email list clean through verification often leads to noticeable improvements in click-through rates. Reaching engaged subscribers increases the likelihood of clicks and conversions, directly boosting your marketing ROI.
Higher CTRs signal stronger engagement, paving the way for more conversions and revenue from your email campaigns.
4. Sales from Email Campaigns
Turning email recipients into paying customers is the main objective of email marketing. Reviewing sales performance before and after using email verification shows how it directly impacts ROI.
Direct Sales Impact
A clean email list boosts deliverability, engagement, and reduces costs:
| Metric | Effect on Sales |
|---|---|
| Revenue per Email | Higher earnings from verified campaigns |
| Conversion Rate | More sales from engaged subscribers |
| Cost per Acquisition | Lower marketing spend per customer |
Measuring Sales Performance
To assess the ROI of email verification, focus on these metrics:
- Revenue per Email: Track how much revenue each email generates and evaluate the total conversion value.
- Cost Comparison: Compare the cost of acquiring customers through verified versus unverified email lists.
- Performance Trends: Analyze trends in performance across different subscriber groups to understand the broader impact.
Real-World Success Metrics

Cost-Benefit Analysis
Regularly verifying your email list results in clear benefits, including:
- Spending less on invalid or inactive contacts.
- Boosting conversion rates by focusing on engaged subscribers.
- Improving deliverability, which opens up more sales opportunities.
- Reducing the cost per acquisition with more precise targeting.
With stronger sales performance in place, the next step is to explore how email verification can further lower customer acquisition costs.
5. Cost to Acquire Customers
Boosting sales is important, but keeping customer acquisition costs (CAC) in check is just as critical for maximizing ROI. Email verification plays a big role here, as a clean, verified email list helps cut down on wasted resources and improves conversion rates.
Breaking Down CAC Components
Here’s how email verification impacts key areas of customer acquisition costs:
| Cost Component | Impact of Email Verification |
|---|---|
| Email Platform Costs | Sending emails to smaller, verified lists reduces expenses. |
| List Management | Fewer undeliverable emails mean lower maintenance costs. |
| Customer Support | Less time spent resolving issues related to bounced emails. |
Measuring Cost Efficiency
To understand how email verification affects CAC, use this formula:
CAC = Total Marketing Costs / Number of New Customers
For email campaigns, monitor these metrics before and after implementing verification:
- Cost per successful delivery
- Cost per conversion
- Total campaign ROI
Real Cost Benefits
Email verification offers clear savings. Industry data shows it’s 5-7 times more expensive to acquire new customers than to retain existing ones. A clean email list allows businesses to focus on engaged subscribers, who are 60-70% more likely to convert.
Cost Optimization Strategies
- Regular List Maintenance: Keep your list clean by verifying emails regularly.
- Smart Segmentation: Use verification data to group audiences by engagement levels, enabling more targeted campaigns.
- Tool Integration: Automate email verification by connecting it with your marketing tools.
Long-term Value Analysis
Email verification doesn’t just save money upfront - it offers long-term benefits like:
- Fewer bounces, improving sender reputation and reducing blacklisting risks.
- Better deliverability, leading to higher conversion rates.
- More accurate campaign performance tracking.
By cutting acquisition costs and increasing efficiency, email verification helps build a foundation for sustainable ROI growth.
"It can cost five to seven times more to acquire a new customer than it does to retain your current customers."
