Understanding Email Deliverability
Definition
Email deliverability rate measures the percentage of emails that successfully reach recipients' inboxes rather than being filtered as spam or bouncing back. It's calculated by dividing the number of delivered emails by the total number of emails sent, multiplied by 100.
Calculation Method
To calculate your deliverability rate:
-
1Count the total number of emails sent in your campaign
-
2Count the number of emails that were successfully delivered
-
3Divide delivered emails by total sent emails
-
4Multiply by 100 to convert to percentage
Key Rules
-
Deliverability rate above 90% is considered excellent
-
Rates below 80% indicate potential deliverability issues
-
Track deliverability separately from open rates
-
Monitor trends over time to identify issues early
Quiz: Email Deliverability
Question 1
If you send 10,000 emails and 9,500 are delivered, what is your deliverability rate?
Using the formula: (Total Delivered / Total Sent) * 100
(9,500 / 10,000) * 100 = 0.95 * 100 = 95%
Correct answer: a) 95%
Email deliverability measures how many of your emails actually reach the recipient's inbox rather than bouncing or being marked as spam.
Question 2
Which scenario shows the best email deliverability performance?
We need to calculate deliverability rate for each option:
a) (8,000 / 10,000) * 100 = 80%
b) (15,000 / 20,000) * 100 = 75%
c) (18,000 / 20,000) * 100 = 90%
d) (7,500 / 10,000) * 100 = 75%
Option c has the highest deliverability rate at 90%, making it the best performance.
Correct answer: c) 18,000 delivered from 20,000 sent
High deliverability rates indicate good sender reputation and email infrastructure, which directly impacts your ability to reach your audience.
Question 3
True or False: An email deliverability rate of 100% means all emails were opened by recipients.
False. Deliverability rate measures whether emails reached the inbox, not whether they were opened. An email can be delivered but not opened, or opened but not acted upon.
Correct answer: False
Question 4
Word Problem: A company sends 25,000 emails with a deliverability rate of 92%. How many emails were successfully delivered?
Using the formula: Delivered = (Deliverability Rate / 100) * Total Sent
Delivered = (92 / 100) * 25,000 = 0.92 * 25,000 = 23,000
Answer: 23,000 emails were delivered
Monitor your deliverability rate separately for different email types (newsletters, promotional, transactional) as each may have different rates.
Question 5
What does a deliverability rate of 70% indicate about your email program?
A 70% deliverability rate is significantly below industry standards (typically 85-95%). This indicates serious deliverability issues that require immediate attention, such as sender reputation problems, spam complaints, or technical issues with the email infrastructure.
Correct answer: c) Poor performance requiring attention
Don't confuse deliverability with engagement metrics like open rates or click-through rates. Deliverability is the foundation - if emails don't reach the inbox, engagement metrics become irrelevant.
Q&A
Q: How can I improve my email deliverability rate?
A: Improving email deliverability requires addressing multiple factors:
Sender Reputation Management:
- Domain Authentication: Implement SPF, DKIM, and DMARC records
- IP Warm-up: Gradually increase sending volume when starting with new IPs
- Consistent Sending Patterns: Avoid sudden volume spikes
- Complaint Handling: Quickly address spam complaints and unsubscribe requests
List Hygiene:
- Regular Cleaning: Remove hard bounces and inactive subscribers
- Double Opt-in: Verify subscriber intent
- Engagement Tracking: Monitor subscriber activity
- Pruning: Remove long-inactive subscribers
Content Optimization:
- Relevant Content: Send valuable, targeted content
- Subject Lines: Avoid spam trigger words
- Personalization: Use recipient names and preferences
- Testing: A/B test content and sending times
Q: What's the difference between email deliverability and email delivery?
A: While related, deliverability and delivery are distinct concepts:
Email Delivery:
- Measures: Whether emails were accepted by recipient servers
- Tracking: Occurs at the server level
- Scope: Includes emails that may go to spam folders
- Focus: Technical acceptance by mail servers
- Measurement: Happens immediately after sending
Email Deliverability:
- Measures: Whether emails reach the intended inbox (not spam/junk)
- Tracking: More complex, often estimated
- Scope: Only emails that land in primary inbox
- Focus: Actual recipient access to emails
- Measurement: May take hours or days to accurately measure
Essentially, delivery is about technical acceptance by servers, while deliverability is about reaching the intended destination (inbox). However, many ESPs use these terms interchangeably.
