Email Deliverability Metrics: How to know if your emails land in spam?
If you’re struggling with low open or reply rates, you should ensure your emails reach your audience. Whether your emails land in your audience's inbox or spam folder is decided by your email deliverability. Not monitoring your deliverability could mean your emails are landing in spam without you knowing!
Using the right tools and metrics, you can monitor your deliverability, find and fix deliverability problems before they affect your campaign results.
In this article, you’ll discover 6 key deliverability metrics that affect your campaign performance and the easiest way to track them.
How do you track email deliverability?
Email deliverability is your ability to deliver emails right into your target’s primary inbox. In short, your deliverability measures whether your emails successfully reach your audience.
3 main factors affect your email deliverability:
- Your Sender Reputation: If you have a history of sending spam or unwanted email, email providers are more likely to land your emails in spam.
- Technical Setup: If you haven't done your email authentication correctly, your emails could land in spam or not be delivered at all.
- Email Content: Emails with spammy or inappropriate content have a lower deliverability rate.
When monitoring their deliverability, most people confuse “email deliverability” with “email delivery”.
The difference between email deliverability and delivery
Email delivery tells you whether your email was successfully sent to your audience. Email deliverability tells you where your emails land if your audience gets them — in the spam or inbox folder.
While most emails get delivered, they may have low deliverability and land in the spam folder. So it’s important to use the right metrics and tools to monitor your deliverability.
6 email deliverability metrics to track where your emails land
1. Deliverability Score
Your deliverability score measures the ability of your emails to reach your audience's inboxes. It is scored out of 100 based on all the factors that affect your deliverability.
Depending on your email health, your deliverability score could be under 3 different stages:
This stage means you might be blacklisted or have a wrong technical setup. You shouldn’t send email campaigns at this stage as you risk landing in spam.
At this stage, your email address is warmed up & fewer emails are landing in the spam folder. But you should still wait for the green stage to start sending emails.
At this moment, you can start sending emails. Make sure to keep your warm-up & deliverability booster ON before-during-after sending campaigns to keep deliverability high.
Tracking your deliverability score helps you send emails at the right time to keep them away from spam and land in your audience’s inbox.
2. Open Rates
Your open and reply rates indicate whether your emails land in the inbox. If you have open rates of less than 45-50%, chances are your emails are landing in spam.
Your audience won’t open or reply to emails they never saw! So it’s important to keep your emails away from spam and land emails in their inbox.
Here are 3 tips to increase open rates and boost your deliverability:
- avoid using clickbait in your subject lines
- regularly clean your email list to remove inactive subscribers
- use a reputable email service provider that follows industry best practices
You can use an outreach tool like lemlist for detailed reports on your open and reply rates 👇
3. Bounce Rate
Email bounce means an email that couldn't be delivered to your audience. Your email bounce rate is the percentage of emails that couldn’t get delivered, also known as ‘bounced.’
Hard bounces occur when the email address is invalid or no longer exists. Soft bounces occur when an email bounces because of a temporary issue with the receiver’s email address.
Unlike a hard bounce, this doesn’t mean a permanent delivery failure; you can try sending the email again.
A high email bounce rate can ruin your sender reputation and reduce your chances of getting replies. Email providers and spam filters could also permanently block your emails from getting delivered to your audience.
So ensure to keep your bounce rate below 5%.
Here are 3 tips to boost your deliverability and decrease bounce rates:
- use a professional sender domain (for example: firstname.lastname@example.org)
- verify your email list before sending campaigns to avoid hard bounces
- remove all addresses showing “permanent delivery failure" from your email list
4. Spam Complaint Rate
The spam complaint rate measures the percentage of subscribers who mark your emails as spam. A high spam complaint rate can damage your sender reputation and deliverability.
Your average spam complaint rate should be less than 0.08%.
Here are 3 tips to reduce spam complaints and keep a good sender reputation:
- remove all contacts who unsubscribe from your email list
- define a clear ICP and ensure you send emails to people who will find them valuable
- add a double opt-in process so you have explicit permission to send emails to your audience
5. Unsubscribe Rate
The unsubscribe rate measures the percentage of your audience who opt out of your email list. A high unsubscribe rate indicates your audience isn’t finding your content relevant or valuable. It’s still important to add an opt-out option in your emails. This prevents spam complaints and protects your sender reputation.
Here are 3 ways you can use your unsubscribe page to build a relationship with your audience:
- take feedback from people who unsubscribe to improve your email content and targeting
- offer your audience some options to receive fewer emails, less often
- avoid losing touch by sharing other resources or newsletters that they can access 👇
6. Sender Reputation
Your email sender reputation is a score given to you based on how you send emails and how much your audience interacts with them. Email providers use metrics like open and reply rates, sending frequency, etc., to decide your sender reputation.
With a poor sender reputation, email providers are likelier to block or send your emails to the spam folder. This hurts your email deliverability and ruins the performance of your email campaigns.
You can use these 3 tips to keep a high sender reputation score:
- do email warm-up before, during, and after sending email campaigns
- avoid using spam trigger words in your emails
- use a dedicated IP address if you have a high sending volume
